4010 No viable drive groups available in system
Explanation: At least one configured drive group member drive is discovered, but no viable drive groups exist in
the system. Non-viable drive groups cannot expose LUNs to any host because the controller cannot create a complete
data set from the drives that are present.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is not
notified of this alert by e-mail. Alert clears when at least one viable drive group is discovered or created, or when no
drive group member drives are present.
Operator response: Perform the following steps:
1. Insert any missing drives.
2.
If the drives appear to be inserted but are not discovered by the system, perform a Disk Connectivity Diagnosis.
3.
If the controller correctly reports the number of drives, but the missing drives are unavailable, you can either
remove the drives that represent the non-viable drive groups or assimilate those drives so that they can be reused
to create new spares or new drive groups.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
3400 Degraded drive group group_ID
Explanation: Failure of a redundant drive caused the drive group to become degraded, but the drive group is still
viable (a spare is available).
System action: By default, the SAS RAID Module system information indicator is not turned on and the operator is
notified of this alert by e-mail. Alert clears when either of the following events occurs:
v
Rebuild operation has been completed and redundancy of the drive group has been restored.
v
The drive group is deleted.
Operator response: None.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5400 Degraded drive group group_ID - No spare available for rebuild
Explanation: Drive group has become degraded due to failure of a redundant drive. The drive group is viable, but
no usable spare is available for rebuildDrive.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is
notified of this alert by e-mail. Alert clears when a spare becomes available.
Operator response:
Assign a spare drive or insert a qualified replacement drive.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5403 Previously mounted drive group group_ID comprised of drives drive_list was not found and has been
removed from mounted group list.
Explanation: Entire drive group found missing on cold boot.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is
notified of this alert by e-mail.
Operator response: Acknowledge to clear the alert immediately. Add drives to make the group viable. If no
automount occurs, reissue the mount command. (In release 1, you must reboot the system to mount the group when
available.)
