Severity: INFORMATIONAL
Description: During RAID replay of NVRAM, entries associated with a non-existent (offline or missing) aggregate were discovered. Since the volume is not available to replay those NVRAM entries, it will be saved in a system file on the root volume and will be replayed when the aggregate becomes available. This event is issued if the system is able to successfully save the NVRAM RAID entries associated with a non-existent aggregate.
Corrective Action: (None).
Syslog Message: RAID replay detected NVRAM entries for a non-existent aggregate having raidtreeID %s. %d checksum, %d stripe and %d pzero entries were successfully preserved.
Parameters: raidtreeID (STRING): RAIDtree identifier of the aggregate.
nchecksum_saved (INT): Identifies the number of checksum NVRAM entries preserved
nstripe_saved (INT): Identifies the number of stripe NVRAM entries preserved
nblkbuf_saved (INT): Identifies the number of pzero NVRAM entries preserved
