Configuration: Disk Groups and Virtual Disks

You must supply the security key from a security key file that was saved on the 

original storage array. You must provide the pass phrase that was used to 

encrypt the security key file to extract the security key from this file.
For more information, see the PowerVault Modular Disk Storage Manager 

online help topics.

In the AMW, when you select a security enabled physical disk that is not part 

of a disk group, the Secure Erase menu item is enabled on the Physical Disk 

menu. You can use the secure erase procedure to re-provision a physical disk. 

You can use the Secure Erase option if you want to remove all of the data on 

the physical disk and reset the physical disk security attributes. 

Before you complete this option, make sure that the physical disk that you 

have selected is the correct physical disk. You cannot recover any of the data 

that is currently on the physical disk.
After you complete the secure erase procedure, the physical disk is available 

for use in another disk group or in another storage array. Refer to the 

PowerVault Modular Disk Storage Manager online help topics for more 

information on the secure erase procedure.

Guidelines to configure host spare physical disks:

• You can use only unassigned physical disks with Optimal status as hot 

spare physical disks.

• You can unassign only hot spare physical disks with Optimal, or Standby 

status. You cannot unassign a hot spare physical disk that has the In Use 

status. A hot spare physical disk has the In Use status when it is in the 

process of taking over for a failed physical disk.

• If a hot spare physical disk does not have Optimal status, follow the 

Recovery Guru procedures displayed by the MDSM application to correct 

any problem before trying to unassign the physical disk.

• Hot spare physical disks must be of the same media type and interface type 

as the physical disks that they are protecting.
