SMU has many status pages that enable you to monitor the status of your system,
virtual disks, and disk drives. The top panel on many status pages includes an icon
for each virtual disk with information about the selected virtual disk below it. The
following table describes the virtual disk status icons.
Virtual disk is online with all drives working.
Virtual disk is online in a critical state.
The virtual disk can perform I/O functions for data hosts but is not fault
tolerant. It is normal for a virtual disk to be critical while it is initializing
online, or is reconstructing after a drive failure; in both cases, the utility name
and percent complete are shown. If a virtual disk is critical for any reason
other than online initialization or reconstruction, review the status information
and take the appropriate action, such as replacing a disk drive. You can use a
virtual disk in this state but resolve the problem as soon as possible. See
"Troubleshooting Using SMU" on page 195 for more information.
