IBM totalstorage
The ds4000 series is a storage product launched by IBM for medium-sized enterprises. It was upgraded from the fastt series and has enhanced some storage functions. Its products are composed of ds4100 (original
Fastt100) to ds4500 (formerly fastt900) can meet most of the storage needs from the low-end to the middle-end, and provide enterprises with comprehensive products and services at reasonable costs.
It has been widely used in the Chinese enterprise market.
Ds4000 series uses ds4000 Storage Manager
V9.10 manages storage resources, enhances remote image options, and uses the ds4100 option for large-capacity configuration and exp100 serial connection to ds4400
ATA
Expand the Unit to improve and supplement the entry-level and enterprise-level disk system solutions. Its management functions are rich and powerful, and the configuration process is complicated. This time, we will introduce you to the initial configuration steps of this product.
And manage the software configuration process.
Initial setup process
Both IBM ds4000 and IBM fast storage
Manager software for management settings, each fast controller has an RJ45 network cable port, and is configured through the network. Each controller also has a string
Port. You can modify the IP address through the serial port. Insert a section into the RS-232 of Controller A, and the other end is connected to another windows
2000/NT4.0 machine serial port. After completing the settings, connect to Controller B and perform the same operation.
The following uses ds4200 as an example and illustrates the configuration steps in detail: Start a terminal software, such as a Windows Super Terminal, and name the connection, such as ds4200.
Then you need to set the connection serial port correctly. In this example, It is com2. And select the appropriate number of bits per second, generally between 2400 and ~ In the range of 9600. Select none for data flow control.
Now we are connected. Press Ctrl + break to activate the management interface. When press within 5 appears
Seconds: <ESC> for shell, <break> for baud
Press ESC at rate. Enter the connection password. The default value is Infiniti (lowercase letter ). In addition, the waiting time for the management interface to be activated depends on the number of digits selected per second, and the Controller will automatically search
It communicates with the matching speed, so you don't have to worry too much while waiting for activation and mistakenly think it is a connection failure. Because this series of IBM products comes from lsilogic, you can see the Network Management Interface
The lsilogic icon appears.
After connecting to the network, we should set it. Run the netshortset command to set the TCP/IP address of the NIC on the fastt200 controller.
Network port management. Press enter until "My host"
The name line appears. Enter the Controller name if you use DNS to manage it. Enter the IP address of the controller. Press enter until "gateway IP Address"
Address line, enter the address and press Enter. Type the subnet mask. Press enter until you exit at the-> prompt.
After all the settings are complete, we still need the last step. You can enter the netdeskshow command to check whether all the settings are correct. If an error occurs, type netreset set again and reset it.
Finally, enter the sysreboot command to restart the Controller for the configuration to take effect. You also need to provide a command, the syswipe command, which is used to clear all the configuration information of the controller, so it is only used when you confirm that you no longer need any data in the original machine.
Well, the hardware settings of the machine have been completed, and next we will continue to explain the application of the management tool of the storage Manager-DS4000.
Management tool applications for storage Manager-DS4000
Ds4000 Storage Manager is now upgraded to version 9.1, IBM ds4000
Sv9.1 is a powerful storage resource management software. Its main functions include creating hard disk arrays, logical Disk, dynamic Logical Disk capacity expansion, dynamic raid level adjustment, management and allocation of different logical disks
Different host HbA cards and self-check tools: Recovery guru, controller diagnostics, read Link
Status, event date, and support for obtaining IP management addresses from the BOOTP and DHCP servers. Flashcopy and remotemirror.
The software has default IP addresses in Versions later than 8.0:
-Controller A: 192.168.128.101/255.255.255.0
-Controller B: 192.168.128.102/255.255.255.0
The following describes the application steps in detail:
Step 1: Start Storage Manager. After sm9.1 is started, ds4000 series devices are automatically searched. As shown in: Click the first icon in the toolbar.
(Automatically discover new storage subsystems), the system automatically searches for storage devices connected to the network.
The administrator can also manually add ds4000 devices. The administrator can click Add under the edit menu.
Drives will pop up the dialog box for the Administrator to enter the controller IP address. Enter the configured IP address and click Add to add the device. If you have configured two controllers
The IP address of the two controllers. The IP address has been written in the above description.
1. When the management software finds the fastt device, it first displays the details of the device controller and the total idle disk capacity. As shown in. In storage
You can rename an existing ds4000 device in the Manager Management Software. Click Storage
Select Rename for subsystem, and enter the device name determined by the Administrator in the pop-up window to rename the device.
2. The management software recognizes the storage device. Next, it creates a disk partition for the storage device, selects the corresponding raid level, and selects the configuration parameters of the logical partition.
Right-click the idle disk capacity and select create logical drive. In the displayed dialog box, set your default host.
Type and raid level. When the Administrator selects raid
Level, the system provides the available raid level based on the number of existing disks on the storage cabinet, and provides two disk options: manual and automatic. Select manually in most cases
Select disks, which will meet the on-site requirements.
The next step is to select the capacity for creating a logical disk. The default capacity is the remaining capacity of your current maximum Logical Disk. The administrator can
Drive capacity
Fill in the appropriate size value in the text box, and select the corresponding unit in the text box. In the Name text box, the administrator needs to name the array for identification. As shown in the elliptical flag.
When you select custom settings or Recommended settings, you generally select custom settings (as shown in the box ). In this way, you can set the controller (slot
A or slot
B) Logical Disk I/O features (including file system, database, multimedia and custom), split size and Disk Association settings. When you need to create more than two arrays
It is best to turn off the choice when using the controller, which will improve the efficiency of data transmission in the future.
After all the settings are complete, we can see all the information on the main interface. Now the Logical Disk of IBM ds4200 has been created successfully. Next we will introduce the specific configuration of storage partition and other new functions and log specific applications.
We have discussed how to use Storage Manager v9.10 to create a logical disk. Now let's talk about how to create a disk partition. Before introducing the application, I would like to explain the storage partition descriptions of the ds4000 series of products.
There is a premium feature in the ds4000 series of products, which are a series of advanced features not included in the standard configuration, namely
Partition Support feature, flashcopy feature, and remote mirror
Feature ). These functions are all purchased by users as needed. The following describes the storage partitions in detail.
Storage partition support
Feature) allows us to connect to multiple host platforms on a fastt. It works by allocating logical disks to a specific host or host group, also known as Lun
Masking. The advantage of this is that hosts in Different Storage partitions cannot view each other's logical disks, which ensures the security of important information and facilitates data classification and management. Partition
The logic structure is default group, host groups, hosts, host
Ports. Logical disks can be mapped to different levels of logical structures. In addition, even if only one host is connected to this storage server, a storage partition should be defined for it.
When purchasing the ds4000 series, the standard configuration of ds4100 and ds4300 provides a host group that can be upgraded to 4, 8, or 16 storage partitions. The enhanced configuration of ds4300 provides
8 storage partitions can be upgraded to 16 or 64. The standard ds4500 provides 16 storage partitions, which can be upgraded to 64. The standard ds4700 provides 2 Storage partitions, can be upgraded to 4, 8
Or 16; ds4700 enhanced configuration provides 8 storage partitions, which can be upgraded to 16 or 64; ds4800
You must select one of the 8, 16, or 64 storage partitions, so the upgrade is 8 to 16, and 16 to 64.
After introducing the basic information, let's introduce the creation process.
1. Check the partition status
First, check the status of the storage Partition Function to see if it is already in the enabled status, including the quick copy and remote image status. As shown in the red box.
2. Create a server group
Click mappings on the main page.
View tab, which then displays the current storage device ing. You can select the Current Logical Structure in the Information column on the left. Of course, if you haven't created one, only
Undefined mappings and default group. In the undefined
A Logical Disk has been created in mappings and is in the waiting for ing status. Right-click the default group and select define host.
Group to create a server group. In the displayed dialog box, enter the name of the server group and click Create. This completes the creation of a server group. You can create multiple groups by repeating the operation. And figure 3.
3. Add servers to the server group
After creating the server group, add the server. Right-click the created server group and select define.
Host option. In the displayed dialog box, enter the server name. In the lower layer, select the hosts card mapped to the server. The list lists the post information of the existing hosts card.
Identifier set. Click Add after selection. Click Next to select host.
In the type dialog box, select the appropriate host type and complete the settings. Click finash and you will be able to see the hosts and servers you just added on the main interface. In this way, the hosts on the host have been
Establishes a ing relationship with the storage device. 4. See figure 5.
4. Partition logical partitions to storage partitions
The following are the most critical steps. To make the information and materials of various departments of the company independent, you can divide the logical partitions created at the beginning into various storage partitions, in this way, we can ensure that the information is not transmitted, and
Security. The specific step is to right-click the Host group item created at first, and select define Storage
Partitioning option (6). In the displayed dialog box, select the host you want to map.
Group or host, click Next (7), and then enter the page for selecting logical partitions. Add the partitions you want to partition to the storage partition. Click Finish.
. (8 ). However, when the host group is selected, the host
When there is more than one host in a group, the system will map the logical partition to each host, that is, the host
Each host in the group can view the information in the logical partition. When a specific host is selected, only this host can see the information.
The partition information is invisible to other information in the group. Therefore, you must arrange the partition ing according to the actual situation when selecting the partition.
1. Change the raid type
After creating a logical disk, you must use this function if you need to change the configured raid level due to application changes. Note that: back up data in the original array before application.
Right-click the original array to be changed and select raid from the change menu.
Level option. The system displays the raid level that can be changed based on the number of existing disks. select a suitable one. When selected, a warning box is displayed, showing the data
On the selected array will remain accessible during this
Operation. Click Yes. The system refresh the raid again.
The duration of the change is determined by the size of the original array. During this period, a small clock is displayed on the disk, and any other operations on the array will not be used until the operation is completed. ()
2. Add disks to the array
Sometimes, the number of configured hard disks cannot meet your needs. In this case, we need to add some disks. In addition to the hardware, you need to add the added disks and add the added disks to the ds4000 management software so that the system can manage the added disks.
Right-click the array of the disk to be added and select Add free.
Capacity (drives): In the pop-up dialog box, you can select the disk you want to add. The system will list the idle disks on the storage device. After you select the disk, click Add.
A warning dialog box will also pop up. Click Yes to wait for the addition to be successful. After successful, you can see the increase in the array capacity and the increase in the number of disks that make up the array on the main interface. ()
3. Modify cache settings
In some cases, the application performance of the disk array is not ideal. To improve the storage performance, you can check the cache settings of the disk partition without adding additional devices, this is very helpful for improving the storage performance, because the default settings are not completely suitable for all users.
Right-click the disk partition you want to view and select the cache in the change option.
After setting, enter the modify cache settings dialog box. The upper part of the dialog box is the selected disk partition, and the lower part is the specific cache settings. The first and second items are read cache and write cache respectively.
The three items allow the image to write to the cache. If this option is selected, You must select the option based on the actual situation, because using the image to write to the cache may affect the storage performance. The last option is to allow write caching without battery protection. (Institute
Display)
4. Increase the capacity of the logical volume
This function allows the customer to dynamically increase the capacity of the logical volume as needed at any time. However, it must be noted that the logical volume can only be increased or decreased.
The specific step is to right-click the logical volume to add capacity, select increase capacity, and click OK to enter the setting interface, in increase
Capacity
By: Enter the size of the capacity to be added in the text box. The unit is MB, GB, and TB. After setting, a confirmation dialog box is displayed. After Entering yes, you can see that the logical volume is
Increase capacity. (Description)
5. Set a hot backup disk
Hot Backup is a very important feature. during use, if a disk in the array is damaged, if the disk is preconfigured to be overheated, the system will immediately fill in the hot backup disk to act as the broken disk and restore it after it recovers the bad disk. This setting is very important. We recommend that you set it when the disk is redundant.
Step: select the disk to be set to hot backup, right-click the hot spare coverage option, and select manually in the displayed dialog box.
Assign individual
Drives, and then enter yes to complete the hot backup disk settings. To cancel a hot backup disk, select the last manually unassign
Individual drives. ()
So far, an IBM
Ds4000 is complete. Of course, we may encounter various practical problems in the setup process. In the specific application process, the device may encounter various faults, which require us to accumulate in the actual operation process.
Experience. The initial installation and configuration is only the first step, but only after the most basic is completed can more powerful management functions be implemented on this basis.
