Action<br />

In a High Availability system with NVRAM, this would be caused by unprocessed<br />

data in a NVRAM cache of the active logical host that has been down and come up<br />

later. Because of this, NVRAM should not be used in an HA system. The problem<br />

can be solved in this case by getting rid of the NVRAM on the HA system.<br />

In a non-HA system, this can also be caused by stale data in the NVRAM cache. (The<br />

example commands below assume the controller for the array is c1.) To fix for a<br />

non-HA system:<br />

1. Turn off all fast writes on this array and sync any remaining pending writes.<br />

# ssaadm fast_write -d c1<br />

# ssaadm sync_cache c1<br />

2. When you sync the fast writes to the array, all pending writes are physically made<br />

to the disks. Anything that is left in the cache is stale, and thus, it is safe to purge it.<br />

Run the command:<br />

# ssaadm purge c1<br />

3. Turn the fast writes for the disks back on. This command MAY be different on<br />

your system, depending on the disks on which you want fast writes enabled and the<br />

types of fast writes you want:<br />

# ssaadm fast_write -s -e c1<br />
