Reconfiguring Storage Processor (SP) IP address using Navisphere Manager
CLARiiON
CX Series,CLARiiON iSCSI Array.
Description:
Procedure
to reconfigure SP IP address using Navisphere Manager.
Resolution:
The storage processor (SP) IP address can only be set through the /setup page. Please follow the steps give
below.
If this procedure is done with active hosts attached to the array,
ensure that there are no single HBA-attached hosts and that failover software
is configured on each multi HBA attached host. SPs will reboot each time the IP
address change is submitted. Wait to change the other SP's IP
address until the first SP has rebooted.
1.
If
the storage system to be reconfigured is the domain master, select a new domain
master before proceeding.
2.
Make
sure both SPs for which you want to change IP addresses are connected to the
network
3.
If
the array on which you want to set or cannot set the IP address ("problem
array") is in a domain with other arrays, open Navisphere Manager on one
of the other arrays and remove it from the domain using the Configure Domain
dialog.
4.
Open
the setup page for SP A <SP
A IP address/setup> on the array.
5.
Reset
security and domain information for SP-A by pressing the "Reset
Security" button. Select "Yes" and "Submit" to
confirm.
6.
Re-open
the setup page for SP A on the array and restart the Management Server by
pressing the "Restart Management Server" button. Select
"Yes" and "Submit" to confirm.
7.
Open
the setup page for SP B <SP
B IP address/setup> on the array.
8.
Reset
security and domain information for SP B by pressing the "Reset
Security" button. Select "Yes" and "Submit" to
confirm.
9.
Re-open
the setup page for SP B on the array and restart the Management Server by
pressing the "Restart Management Server" button. Select
"Yes" and "Submit" to confirm.
10. Once the Management Server on
SP A and SP B has been restarted, security and domain information will be in an
uninitialized state. You should now be able to set the IP addresses using
the following steps
11. Open a browser and go to <Current SP A IP address/setup>
12. In the IP address field change
the current SP A IP address to the new SP A IP address and click "Apply
Settings". SP A will reboot which may take up to five minutes to complete
13. Go back to SP A's setup page
using the new SP A IP address <New
SP A IP Address/setup>
14. Open a browser and go to <Current SP B IP address/setup>
15. In the IP address field enter
SP B's new IP address and in the Peer IP Address field enter SP A's new IP
address and click "Apply Settings". SP B will reboot which may take
up to five minutes to complete.
16. Go back to the SP B setup page
<new SP B IP
Address/setup> and click "Restart Management
Server". Select "Yes" and "Submit" on the pop up
screen.
17. Go to SP A setup page <New SP A IP Address/setup>
(You may already be there due to step number 12) and click "Restart
Management Server". Select "Yes" and "Submit" on
the pop up screen. This will update the peer IP address on SP A.
18. If the array will be back in a
domain with other arrays, re-add it to the existing domain.
Security will automatically be initialized by obtaining the necessary
information from the domain master. If it was originally in the domain and it
was the domain master you can now select it as the domain master again.
If the array is not to be in a domain, open Navisphere Manager on SP A of the
array. You should now be prompted to initialize security. Select
"Yes" and add a global username and password.
