Corrective
Action:
This is an expected behavior and no action is required.
Virtual disk size in decimals is not supported while creating a VD
Likely Cause: After entering the disk size value, changing the virtual disk size unit from MB to GB or GB to TB and so
on changes the disk size value.
Corrective
Action:
It is recommended to select the virtual disk size unit before specifying the disk size value.
Cannot create a virtual disk
If you are unable to create a virtual disk, check the following causes:
1. The physical disk is not displayed.
2. Insufficient free space available on the selected physical disks.
3. Incorrect number of physical disks selected for the desired RAID level .
4. The desired physical disk is unavailable.
5. The system already has a maximum of 30 virtual disks.
The physical disk is not displayed
This error might be because:
1. The controller cannot communicate with the physical disks.
2. A cable might be loose or defective.
3. The physical disk might be a SAS drive.
Re-seat the physical disks in the backplane and check their cables.
Insufficient free space available on the selected physical disks
There must be sufficient available free space on the physical disk used by the virtual disk.
Incorrect number of physical disks selected for the desired RAID level
For details about RAID levels and the allowable number of physical disks used with each RAID level, see understanding RAID
levels in RAID Technology Guide at www.dell.com/manuals.
The desired physical disk is unavailable
Determine whether the physical disk:
1. Is a dedicated hot spare and unavailable for use in another virtual disk.
2. Is full or has insufficient available capacity.
The system already has a maximum of 30 virtual disks
Delete unused virtual disks.
CAUTION: Deleting a virtual disk destroys all data on the virtual disk.
