Symptom Need to change CLARiiON SP's IP address

Cause Purpose of this solution is to describe a methodology for easily

changing the SP IP addresses on Celerra Integrated platforms running NAS

5.5.31 or later, or any version of NAS 5.6.

Note: The storage processors (SPs) are systematically rebooted during thi

s operation.

Fix

Current generation integrated Celerras use Proxy ARP instead of NAT by

default.

With this, the /nas/sbin/CLARiiON_mgmt tool was introduced, which can

be used to change the public IP addresses for the CLARiiON storage process

ors.

Here are the steps to change the public CLARiiON SP addresses. In the f

ollowing example, SP A's IP address is changed from .6 to .10,

and SP B's from .7 to .11.

1. Make sure Proxy ARP is running and both SPs can be contacted using

their current IP addresses.
