All data on a logical drive is lost when it is deleted. Make sure you backup any important data on the logical drive - HP Surestore Disk Array 12h | System Administrator's Guide for HP-UX, MPE, and W - Page 249

Utilities for Windows NT Adding a Disk Including a Disk Manually A disk must be included in the disk array configuration before it can be used by the disk array. There are two ways to include a disk: • You can enable Auto Include, which will automatically include a disk when it is inserted into the - HP Surestore Disk Array 12h | System Administrator's Guide for HP-UX, MPE, and W - Page 251
The rebuild priority determines how quickly a rebuild completes. It allows you to balance the servicing of host I/Os with the rebuilding of the disk array. The same rebuild priority is used for both auto rebuilds and manual rebuilds.
