How to restore VNX Unify to the status where VIA can be used for initialization

Source: Internet

Tags ssh file permissions

Fault symptom:

The VNX uniied series can only perform partial File initialization once when using VIA. If the configuration fails or the VIA window is closed halfway, VIA cannot scan the storage again.


Solution:

1. Use Putty and other software to log on to CS0 through the string line. Note that the string line here must be a random string line. Because the CS interface is very narrow, other string lines cannot be inserted. Serial port speed 19200

 

A) log on to CS0 via serial port. Username: root Password: nasadmin

 

Note: If the storage is configured with dual CS, you can disable CS1, unplug the cable, and then add CS1 after configuring, or set the dual-CS configuration as follows.

 

B) record the MAC address of eth3 of CS0 and CS1 from the tags on the CS front panel, or run the following command to view the MAC address and record the IP address of eth3:

 

#/Sbin/ifconfig eth3

 

2. Run the following command:

 

#/Nasmcd/sbin/clariion_mgmt-info

 

If:

 

Error 12: Not configured

 

It indicates that the proxy ARP is not configured. You can directly jump to step 3. If the Proxy ARP has been configured, run the following command to restore the SP ip address to the factory settings:

 

#/Nasmcd/sbin/clariion_mgmt-stop

 

Returned information:

 

Checking if running as root... yes

 

Checking if model is supported... yes

 

Checking for integrated system... yes

 

Checking if interface eth3 is configured... yes

 

Checking if SP (10.241.168.206) is up... yes

 

Checking if SP (10.241.168.207) is up... yes

 

Step 1/12 [28185788417]: Changing spa ip address.

Step 8/12 [28185788422]: Waiting for SPB to restart.

 

Waiting for SPB to go down... done (18 secs)

 

Step 9/12 [28185788426]: Waiting for ping response from SPB.

 

Waiting for 128.221.253.201 to respond ...... done (14 secs)

 

Step 10/12 [28185788428]: Waiting for CLARiiON software to start on SPB.

Waiting until SPA sees 128.221.253.201 in the domain... done (2 secs)

 

Step 11/12 [28185788430]: Updating NAS database with spb ip address.

 

Updating SYMAPI database with new CLARiiON IP addresses... done (20 secs)

 

Step 12/12 [28185788434]: Removing Proxy ARP for SPB on Control Station

 

Removing host specific route for SPB

 

Removing rules that allow outbound traffic from SPB

 

Removing ARP entry for SPB

 

Updating/etc/hosts entry for SPB

 

FINISH: Operation took a total time of 4 minutes 35 seconds to complete.

 

3. Run the following command to check whether the "S95cable_check" file exists in/etc/rc3.d:

 

# Cd/etc/rc3.d

 

# Ls-la S95cable_check

 

4. If the file exists, you can directly jump to the next step. If the file does not exist and has not been backed up before, you need to extract the file from the NAS disc of the corresponding version and transmit the file to the storage through software such as WinSCP.

 

The file path on the CD is as follows:

 

Emcnas7.1.47.5 _ DVD. isoEMC

 

The attachment contains files required by version 7.1.47.5, which can be extracted directly.

 

5. Use a network cable to connect to eth3 and use WinSCP to log on to the eth3 ip address. Copy the file to the/etc/rc3.d/directory.

 

6. Change file permissions

 

# Chmod 755 S95cable_check

 

7. Delete temporary files

 

# Rm-rf/tmp/. factory *

 

# Fm-rf/tmp/factory *

 

8. Run the vi command to modify the hosts file and delete the host name of CS0.

 

# Vi/etc/hosts

 

Delete the host name and ip address fields related to CS0. For dual-CS configuration, delete the host name and ip address fields on CS1.

 

9. For single-CS configuration, skip to step 1. For dual-CS configuration, perform the following steps:

 

A) log on to CS1 through SSH from CS0

 

# Ssh 128.221.252.101

 

B) stop the NAS service on CS1

 

#/Sbin/service nas stop

 

C) log out of CS1 SSH and stop the NAS service on CS0.

 

#/Sbin/service nas stop

 

D) log on to the root account of CS1 through a serial port and perform the following operations:

 

A. Copy the S95cable_check file to/etc/rc3.d (this operation requires logging on to eth3 of CS1 with WinSCP)

 

B. Delete the host name and IP address of CS1 in the/etc/hosts file.

 

C. Delete the/etc/sysconfig/network-scripts/ifcfg-eth3 configuration file

 

D. Restart CS1 until the following information is displayed:

 

Waiting for VNX Installation Assistant to continue ....

 

10. Delete the/etc/sysconfig/network-scripts/ifcfg-eth3 configuration file on CS0

 

11. Restart CS0 until CS0 displays the following information:

 

Waiting for VNX Installation Assistant to continue ....

 

12. Start VIA to initialize VNX uniied
