Stale partitions are listed on creating a virtual disk for Linux
Description: When a virtual disk is created using physical disks that were earlier used for creating Linux virtual disk, we
see some Linux partitions present during OS installation.
Solution Whenever we create or delete a virtual disk, only the superblock metadata is modified. The partition table
of the virtual disk which is stored at logical LBA-0 is not modified. Hence when we re-create a virtual disk,
we still see the previous partitions being listed.
● During OS installation these partitions can be deleted using the OS installer.
● To not list the partitions, if supported you can perform cryptographic erase of the physical disk and
then create a virtual disk from the HII.
NOTE: Performing cryptographic erase will delete all the data on the physical disk.
Rebuilding a virtual disk the global hot spare is not listed as online
in HII or iDRAC
Description: After the rebuild of a virtual disk is completed using the global hot spare the status of the disk is not listed
as online, instead the status of the disk is listed as ready.
Solution This is an expected behavior. No action is required.
S150 displays 22 virtual disks on POST instead of 30 virtual disks
Description:
The maximum number of virtual disks that are supported in OPROM is 24.
● If the physical disks are connected, only 22 virtual disks are displayed.
● If an optical drive is connected, and a DVD disk is inserted into the optical drive, then 23 virtual disks
are displayed.
● If two optical drives with DVD disks inserted into the optical drives are connected, then 24 virtual
disks are displayed.
Corrective
action:
This is an expected behavior and no action is required.
S150 displays 43 virtual disks on POST instead of 30 virtual disks
Description:
The maximum number of virtual disks that are supported in UEFI is 30.
● You cannot create more than 30 virtual disks.
● During virtual disk management and re-scan operations, you can see only 30 virtual disks. This is an
expected behavior.
● If a drive or drives with virtual disks are imported from another system, then 43 virtual disks are
displayed.
Corrective
action:
This is an expected behavior and no action is required.
Display of failed virtual disk in HII
Description:
If any failed virtual disk is present in the system, then it is not listed under View Virtual Disk Properties.
The failed virtual disk is listed under Select Virtual Disk Operations and Manage Virtual Disk
Properties.
