NOTE: The Pause Check Consistency task updates the virtual disk State property to Resynching Paused immediately. The
Progress property may continue to increment for up to three seconds. This time delay occurs because the polling task may
take up to three seconds to query the task information and update the display.

Virtual disk troubleshooting
Rebuilding of virtual disk does not work
Rebuilding of virtual disk does not work in the following situations:
● The virtual disk is non redundant — For example, a RAID 0 virtual disk cannot be rebuilt because RAID 0 does not provide
data redundancy.
● There is no hot spare assigned to the virtual disk — As long as the virtual disk is redundant, to rebuild it:
○ Remove the failed physical disk and replace it. A rebuild automatically starts on the new disk.
○ Assign a hot spare to the virtual disk and then perform a rebuild.
● You are attempting to rebuild onto a hot spare that is too small — Different controllers have different size requirements for
hot spares.
● The hot spare is unassigned from the virtual disk — This occurs on some controllers if the hot spare is assigned to more
than one virtual disk and is being used to rebuild a failed physical disk for another virtual disk.
● The virtual disk includes failed or corrupt physical disks — This situation may generate alert 2083. For information on alert
messages, see the Server Administrator Messages Reference Guide at Dell.com/support/home.
● The rebuild rate setting is too low — If the rebuild rate setting is quite low and the system is processing a number of
operations, then the rebuild may take an unusual amount of time to complete.
● The rebuild is canceled — Another user can cancel a rebuild that you have initiated.
Rebuilding of virtual disk completes with errors
About this task
A rebuild completes with errors when a portion of the disk containing redundant (parity) information is damaged. The rebuild
process can restore data from the healthy portions of the disk but not from the damaged portion.
When a rebuild is able to restore all data except data from damaged portions of the disk, it indicates successful completion while
also generating alert 2163. For information about the event and error messages generated by the system firmware and agents
that monitor system components, go to qrl.dell.com > Look Up > Error Code, type the error code, and then click Look it up.
The rebuild may also report sense key errors. In this situation, take the following actions to restore the maximum data possible:
Steps
1. Back up the degraded virtual disk onto a fresh (unused) tape drive.
