263 Warning The indicated spare disk is missing. Either it was removed or it is not responding.
Recommended actions:
● Replace the disk with one of the same type (SSD, enterprise SAS, or midline SAS) and the
same or greater capacity.
● Configure the disk as a spare.
266 Info. A volume-copy operation for the indicated master volume has been aborted by a user.
Recommended actions:
● No action is required.
267 Error A volume-copy operation completed with a failure.
This event has two variants:
1. If the source volume is a master volume, you can remount it. If the source volume is a
snapshot, do not remount it until the copy is complete (as indicated by event 268).
2. Possible causes are the pool running out of available space and crossing the high threshold,
volumes being unavailable, or general I/O errors.
Recommended actions:
● For variant 1: No action is required.
● For variant 2: Look for other events logged at approximately the same time that indicate a
pool space or volume failure. Follow the recommended actions for those events.
268 Info. A volume-copy operation for the indicated volume has completed.
Recommended actions:
● No action is required.
269 Error A partner firmware update operation could not be performed.
This event has these variants:
1. System health is insufficient to support firmware partner update.
2. System has unwritable cache data present.
3. Unable to determine if unwritable cache data is present.
4. Incompatible firmware versions in the controller modules.
5. Incompatible firmware is present in the system.
Recommended actions:
● For variant 1, 2, or 3: You must resolve this condition before the firmware update
will proceed. Log into the system and run the show system command to identify
unhealthy components and find recommendations for restoring system health. The check
firmware-upgrade-health command can be used to verify that the system is ready
for firmware upgrade. For unwritten cache data, use the CLI show unwritable-cache
command.
● For variant 4: This feature can be manually re-enabled after both controller modules are
running compatible firmware.
