Issue :
- How to Change EMC Storage Management IP Address without Reboot
- Customer needs to change the IP address, subnet mask , default gateway of a CLARiiON or VNX for Block storage processor (SP)without rebooting the Storage Processors (SP)
Scenario : EMC CLARiiON or VNX BLOCK Storage System
Solution :
1) Download and Install Naviseccli utility
2)Run following command
Add Security Parameters
For SPA
naviseccli -User admin -Password password -Address 172.XX.XX.XX -Scope 0 -AddUserSecurity
For SPB
naviseccli -User admin -Password password -Address 172.XX.XX.XX -Scope 0 -AddUserSecurity
Get the info about existing SPs
For SPA
naviseccli -h 172.XX.XX.XX networkadmin -get
For SPB
naviseccli -h 172.XX.XX.XX networkadmin -get
Change the IP Address
For SPA
naviseccli -h 172.XX.XX.XX networkadmin -set -address 172.XX.XX.XX -subnetmask 255.255.255.0 -gateway 172.XX.XX.XX
naviseccli -h 172.XX.XX.XX networkadmin -set -address 172.XX.XX.XX -subnetmask 255.255.255.0 -gateway 172.XX.XX.XX
Congratulations! IP Address is changed!!!
Detailed Procedure from EMC Support :
naviseccli commands will not cause SPs to reboot.
Using the CLARiiON/Block setup page in GUI causes a reboot
Any name change requires SP reboot.
Instructions to update the SPs IP addresses, netmask and gateway IPs is below:
Before you begin:
Check to be sure the array is not part of a storage domain
Check that all hosts have dual-Fibre connectivity and that failover software is working correctly
In Unisphere, Under Domains-> Local - for the array he logged into.
Next, clicked on local, only one array should show up - the array the IPs are being change on
Connect to the Array via the naviseccli
Verify the current settings and record them.
Command to check the current SP settings:
CMD:
naviseccli -h <current SPaIP> networkadmin -get
SAMPLE OUTPIT:
Storage Processor: SP A
Storage Processor Network Name: A-IMAGE
Storage Processor IP Address: 10.241.xx.xx
Storage Processor Subnet Mask: 255.255.xx.xx
Storage Processor Gateway Address: 10.241.xx.xx
Repeat for SPB
Verify the new information before hitting <enter>
Once the new ipaddresses are set, if any mistakes were made, it may be necessary to attach directly to the array to correct via the service or serial port
SAMPLE:
naviseccli -h <current SPaIP> networkadmin -set -address <newSPaIP> -subnetmask <if changing-new IP> -gateway <if changing-newIP>
At this point theCustomer's network would need to be changed for the new array IP addresses.
Ping the new SP IP and be sure you are able to connect to it before proceeding to SPB.
Once the SPA is updated, contacted, and accessible, Complete changes on SPB
