Erasing Secure Physical Disks

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.

CAUTION: Possible loss of data access – The Secure Erase option removes all of the data that is currently on the physical disk. This action cannot be undone.

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.

Configuring Hot Spare Physical Disks

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.

Configuration: Disk Groups and Virtual Disks
