Physical disk issues
Physical disk in failed state
Issue: One of the physical disks in the disk array is in the failed state.
Corrective Action: Update the Shared PERC 8 cards to the latest rmware available at Dell.com/support. Replace the physical disk
with a working one which is compatible with the old physical disk and is of equal or greater capacity.
Capable speed of a drive being shown as blank
Issue: Capable Speed under Physical Disk → Properties is Blank for 12 Gbps SAS drives.
Corrective Action: The drive is functional and is operating at 6 Gbps SAS speeds. For further details contact Dell Technical Support.
For more information, see Getting help.
Physical disk displayed as Blocked by management application
Issue:
One or more physical disks are displayed as Blocked and cannot be congured.
Corrective Action: Ensure that the physical disk is supported by SCSI-3 Persistent Reservation (PR). Update the physical disk and
Shared PERC 8 to the latest rmware available on Dell.com/support.
NOTE: If you are using the Dell Update Package (DUP) to update the physical disk, shutdown all the server modules and power
cycle the chassis after the update is completed.
Multiple disks become inaccessible
Issue:
Multiple disks become simultaneously inaccessible.
Corrective Action: Multiple physical disk errors in a single array indicate a failure in cabling or connection and can involve loss of data.
Perform the following steps to recover the virtual disk:
CAUTION: Follow the safety precautions to prevent electrostatic discharge.
1 Turn o the system, check the cable connections, and reseat the physical disks.
2 Ensure that all the disks are present in the enclosure.
3 Turn on the system and enter the Chassis Management Controller (CMC).
4 Use the CMC to import the foreign conguration that is detected or clear the foreign conguration.
NOTE: For information about importing or clearing foreign conguration, see the Dell Chassis
Management Controller for Dell PowerEdge VRTX User’s Guide at Dell.com/poweredgemanuals.
If the virtual disk is redundant and transitioned to Degraded state before going Oine, a rebuild operation starts
automatically after the conguration is imported. If the virtual disk has gone directly to the Oine state due to a
cable pull or power loss situation, the virtual disk is imported in its Optimal state without a rebuild occurring.
