How to change the administrative address of the VNX Storage Processsor and control station

Preparatory work

A) Lists the new IP address lists for VNX Storage Processsor and control station.

b) with the Serial line connection CS0, and through the putty landing. Note: From the back of the control station, the serial port is at the far right.

c) Landing putty, configuration parameters are as follows:

• Bits per second:19200


• Data bits:8


• Parity:none


• Stop Bit:1


• Flow Control:none


• Telnet Terminal Id:ansi

D log in as user nasadmin, into the root directory $ su root

Scenario One: New IP address and original address in different network segments

1. Suspend the SP's proxy ARP with the following command. At this point the original IP address will no longer respond to any ARP request, that is, the original address is invalid. Restore to the factory admin address 128.221.252.200 and 128.221.252.201.

#/nas/sbin/clariion_mgmt-stop

# ping 128.221.252.200 [SPA]

# ping 128.221.253.201 [SPB]

2. Change the IP address of the CS0 and verify that:

A) Change the IP address of the CS0 and verify that:

# nas_cs-set-ip4address 10.240.210.110-ip4netmask 255.255.255.0-ip4gateway 10.240.210.1

Ok

# nas_cel-list

ID Name owner Mount_dev channel Net_path CMU

0 c250 0 10.240.210.110 FNM001046001132007

# grep /etc/hosts

10.240.210.110 c250.emc.com c250

b wait 5-15 minutes, CS0 's new IP address will be updated to admin domains domain.

#/nas/sbin/navicli-h 128.221.252.200 domain-list

#/nas/sbin/navicli-h 128.221.253.201 domain-list

Note: The final result on the two SP will display the new IP address of CS0.

c if necessary, plug the port of the management port to another switch.

D if only a single control station, go directly to step 5. If you have two control station, continue to the next step.

3. Switch from CS0 to CS1, modify CS1 IP address and update to admin domain.

A) switch from CS0 to CS1:

#/nas/sbin/cs_standby-failover

The system would reboot, do your wish to continue? [Yes or No]: Yes

Failing over from Primary control station ...

b) with the Serial line connection CS1, and through the putty landing. Confirm that CS1 is the current primary control station.

#/nas/sbin/getreason

11-SLOT_0 Secondary Control Station

10-slot_1 Primary control station--> shows "primary" here

5-slot_2 contacted

5-slot_3 contacted

# Ps-ef |grep BOXM

# Ps-ef |grep Nas_m

C Change the IP address of the CS1 and wait 5-15 minutes to confirm that CS0 's new IP address will be updated to admin domain.

# nas_cs-set-ip4address 10.240.210.111-ip4netmask 255.255.255.0-ip4gateway 10.240.210.1

Ok

# nas_cel-list

#/nas/sbin/navicli-h 128.221.252.200 domain-list

#/nas/sbin/navicli-h 128.221.253.201 domain-list

# grep /etc/hosts

10.240.210.111 Cs1_250.localdomain cs1_250

D if necessary, plug the port from the management port to another switch.

4. Switch from CS1 back to CS0, waiting for CS0 IP address to be updated to domain again.

A) switch from CS1 back to CS0.

#/nas/sbin/cs_standby-failover

The system would reboot, do your wish to continue? [Yes or No]: Yes

Failing over from Primary control station ...

b) with the Serial line connection CS0, and through the putty landing. Confirm that CS0 is currently primary control station.

# Ps-ef |grep BOXM

# Ps-ef |grep Nas_m

#/nas/sbin/getreason

10-SLOT_0 Primary Control Station

11-slot_1 Secondary Control Station

C Wait a few minutes to update CS0 IP into domain again.

#/nas/sbin/navicli-h 128.221.252.200 domain-list

#/nas/sbin/navicli-h 128.221.253.201 domain–list

5. The entire process takes approximately 15 minutes to enable proxy ARP on spa and SPB, configure a new IP address, and confirm that the new address takes effect.

#/nas/sbin/clariion_mgmt-start-spa_ip 10.240.210.112-spb_ip 10.240.210.113

#/nas/sbin/getreason

# Nas_storage-c-A

# ping 10.240.210.112

# ping 10.240.210.113

#/nas/sbin/navicli-h 10.240.210.112 domain-list

#/nas/sbin/navicli-h 10.240.210.113 domain–list

6. Login Unisphere, verify that the IP address has been modified successfully.

Scenario Two: The new IP address and the original address are on the same network segment

1. Change the IP address of the two SP with the following command to confirm that the new address is valid.

#/nas/sbin/clariion_mgmt-modify-spa_ip 10.240.200.52-spb_ip 10.240.200.53

# ping 10.240.200.52

# ping 10.240.200.53

# tail/etc/hosts

10.240.200.53 b_fnm00104600113 SPB # CLARiiON SP

# Nas_storage-c-A

Discovering storage on c250 (may take several minutes)

Done

#/nas/sbin/navicli-h 10.240.200.52 domain-list

#/nas/sbin/navicli-h 10.240.200.53 domain–list

2. Change the IP address of the CS0 and confirm that the new address is updated to domain.

# nas_cs-set-ip4address 10.240.200.50-ip4netmask 255.255.255.0-ip4gateway 10.240.200.1

Ok

# grep /etc/hosts

10.240.200.50 c250.emc.com c250

3. For VNX devices with two control station, you need to switch from CS0 to CS1, change the CS1 IP address, and wait for the CS1 new address to be updated to domain.

A) switch from CS0 to CS1

#/nas/sbin/cs_standby-failover

b) Login CS1 and confirm that CS1 is the current primary control station.

#/nas/sbin/getreason

11-SLOT_0 Secondary Control Station

10-slot_1 Primary Control Station

5-slot_2 contacted

5-slot_3 contacted

C Change the IP address of the CS1 and confirm that the new address is updated in domain.

# nas_cs-set-ip4address 10.240.200.51-ip4netmask 255.255.255.0-ip4gateway 10.240.200.1

4. Switch from CS1 back to CS0, waiting for CS0 IP address to be updated to domain again.

A) switch from CS1 back to CS0

#/nas/sbin/cs_standby-failover

B Login CS0 and confirm that CS0 is the current primary control

#/nas/sbin/getreason
