Action

In a High Availability system with NVRAM, this error would be caused by unprocessed data in a NVRAM cache of the active logical host that has been down and started again later. Because of the possibility of error, NVRAM should not be used in an HA system. The problem can be solved in this case by removing the NVRAM on the HA system.

In a non-HA system, this error can also be caused by stale data in the NVRAM cache. (The example commands that follow assume the controller for the array is c1.) To fix for a non-HA system:

1. Turn off all fast writes on this array and sync any remaining pending writes:

   # ssaadm fast_write -d c1 # ssaadm sync_cache c1

2. When you sync the fast writes to the array, all pending writes are physically made to the disks. Anything that is left in the cache is stale; thus, it is safe to purge it. Run this command:

   # ssaadm purge c1

3. Turn on the fast writes for the disks. This command might be different on your system, depending on the disks where you want fast writes enabled and the types of fast writes you want:

   # ssaadm fast_write -s -e c1
