Probable Cause: This occurs when Dell EMC PowerEdge Servers perform a cold reboot.
Corrective
Action:
These events can be safely ignored as there is no functionality loss.
Characters are limited when entering a virtual drive
name
Issue: Limitation in the number of characters while creating a virtual disk name
Corrective
Action:
It is recommended that you use maximum of 10 characters while naming the virtual disk.
VMFS datastore is disabled from YX5X of PowerEdge
systems that are shipped with VMware ESXi installed
on BOSS-S2
Issue: Installation of ESXi on a BOSS-S2 device does not have VMFS datastore enabled by default, and disables
VMFS if you use a custom image for installation. This issue occurs when using ESXi version 6.5.x or later
on the BOSS-S2 card.
Corrective
Action:
When you have VMware ESXi installed on BOSS-S2, it is recommended that you use the BOSS-S2 device
only as a boot device and disable VMFS if you are installing a custom image. For more information, see
https://kb.vmware.com/s/article/2004582 and https://kb.vmware.com/s/article/2145210.
NOTE: The scratch partition is created and configured during VMware ESXi installation in addition to
boot support on BOSS-S2.
One or more physical disks are not detected by the
operating system
Issue:
One or more physical disks are not detected by the operating system.
Probable Cause: A physical disk will not be presented to the operating system in the following scenarios:
● There is RAID metadata on the physical disk and no RAID metadata on the controller.
● The BOSS-S2 controller has RAID metadata on it and the physical disk does not have the RAID
metadata on it.
Corrective
Action:
If the RAID metadata is on the controller, follow the steps listed in Clear Controller Configuration.
If the RAID metadata is on the physical disk, follow the steps specified in Erase physical disk.
Alternatively, if you want to keep the RAID drive, refer to Virtual Disk Not visible to Operating System
Virtual disk is not detected by the operating system
Issue:
In RAID mode a virtual disk is not appearing for use by an operating system.
Probable Cause: Virtual disks will not be presented to the system if they are not native to the controller.
Corrective
Action:
Import the virtual disk via HII as specified in section Virtual Disk Import.
