EMC Storage Management

Chapter I. EMCProduct Introduction1.1.Noun Introduction

dae--disk cage. The cabinet used to mount the disk.

Disk Processor enclosure--a controller unit with disks. The main equipment of the storage system, including the system disk, controller, power module, cache and CPU of the storage system, is the core device of the storage system reading and computing data.

Standby Power supply--Standby power supply. The purpose of this standby power supply is to protect the data from loss of data in the event of a power outage by continuing to supply power until an unexpected power outage occurs until data in the temporary storage controller cache is written to the hard disk. The standby power supply can support approximately 3-5 minutes in full-load operating mode, which is enough time to write data from the cache to the hard disk.

3.1.planning for storage-tier space

This is a total of 15 600GB 15K disk configuration, the following plan:

3.2.Create raid Group

This document is an example of RAID group 1, RAID Group 2, and RAID group 499 .

Example one: Create RAID Group 1:

Under the storage, point storage pools,

For example, select Pools to the right of the raid Groups, and then click Create

Set Storage Pool id:1

Set up RAID configuration:raid1/0

Select disk, we recommend using manual, select Manual and click Select.

Select the disk you want to configure from the left, click the right arrow, select on the right, and click OK.

Confirm the selected disk and click OK.

Click Yes

Successfully created RAID Group 1.

Example 2: Creating a RAID Group 2

Set Storage Pool id:2

Set up RAID configuration:raid5

Select disk, we recommend using manual, select Manual and click Select.

Select the disk you want to configure from the left, click the right arrow, select on the right, and click OK.

Confirm the selected disk and click OK.

Click Yes.

Successfully created RAID Group 2. The Riad group3~5 is configured with RAID Group 2 and is not duplicated here.

Example 3: Create a hotspare

Set Storage Pool id:499

Set up RAID configuration:hot Spare

Select disk, recommend using manual, select Manual and Click Select, select the disk you want to configure.

Successfully created RAID group 499. Follow this procedure to create a RAID group 498 and RAID group 497.

After you are done, you can view the raid Group you created , select the raid you created, and click Properties to view the attributes.

3.3.Partitioning LUNs

Build LUNs on the created RAID group, select Raid group right, choose Create LUN

Set the user capacity to the size you want (this is Max, which is the whole raid to build a LUN), the latter can be gb/mb, etc.;

Set the LUN ID, uniqueness principle, the following can give the LUN name;

Set number of LUNs to create multiple LUNs at the same time.

Click Advanced to assign the default owner to an SP, it is recommended to distribute the average to spa and SPB, and if you create multiple LUNs at the same time, you can select Auto, and the storage will be automatically distributed evenly.

Click Yes

Click OK. Follow this method to complete the creation of the remaining LUNs.

After you are done, you can view the created LUNs, select the LUN you created, and click Properties to view the attributes.

3.4.host HBA Card Master book and PowerPath installation

In this project, the Windows platform uses the agent autoenrollment, the Linux platform uses the manual registration.

(1) Windows Platform HBA card registration and PowerPath installation.

Install Navihostagent-win-32-x86-en_us-6.29.6.0.35-1.exe on the server and

emcpower.x64.signed.5.5.sp1.b512. EXE software, you need to restart the server after installation.

(2) Linux Platform HBA card registration

Under Hosts, click Initiator

You can see the device connected to the storage, this example manually registered UAFDB01 This server, other Linux servers registered in the same way.

Log in to the fibre switch to perform switchshow, find the HBA wwn for UAFDB01, and look for the HBA wwn in the diagram below, check click Register.

Set Initiator Type:clariion/vnx

Set Failover mode:active-active Mode (ALUA)-failovermode4

Set host Agent information

Host NAME:UAFDB01

IP address:168.33.2.80

Click Yes

Successful registration of the first link, each server has 4 links, so the remaining 3 are registered to this host. The second link is registered below.

Select the second link and click Register.

In the pop-up window,

Set Initiator Type:clariion/vnx

Set Failover mode:active-active Mode (ALUA)-failovermode4

4.1.storage System on/off sequence

Boot order: fibre switch à storage device à host system

Shutdown sequence: host system à storage device à fibre switch

4.2.VNX5100 Boot Step

U check that all power supply lines are connected properly, loose or altered and corrected.

starting from the top of the cabinet, open the power supply for all DAE disk enclosures from up to down.

U Open two battery (SPS) switch at the bottom of the enclosure

U boot complete.

Pre-boot precautions: U disk array before power-up, to ensure that the enclosure is cooling and working properly, make sure that each slot in the enclosure is plugged into the hard drive and the wind shield. You need to ensure that the ――spe or DPE has at least one working SP before powering on, and that each DAE must have at least a single working LCC.

4.3.VNX5100 shutdown Steps

U turn off the two battery (SPS) switch at the bottom of the cabinet and wait about 3 minutes until the data in the VNX5100 storage write cache is fully written to the hard disk, you can see that the battery light is completely off, and that the power led on the SPE chassis and the Dae-os disk chassis is off when the battery stops powering.

U turn off the power switch of the SPE chassis and the Dae-os disk chassis

from bottom to top, switch off all DAE disk enclosures (inside the enclosure)

U turn off the cabinet rear side cabinet main switch

U shut down the machine to complete.

Precautions before shutting down: U Warning: do not turn off any of the power supplies in the Spe,dpe,dae enclosure before turning off the two battery (SPS) power switch, otherwise it is likely to cause serious errors and result in data loss! You need to wait 3 minutes even after you turn off the two-battery (SPS) power switch until the data in the CX storage write cache is fully written to the hard disk to turn off power to the enclosure such as the Dae,spe or DPE U Stop all applications for VNX disk array access so that all I/O can be written back to the first 5 disks from the SP's write cache. U If you have a UNIX server connected to an VNX disk array, you must umount all the file systems associated with the CX disk array on the UNIX server.
