armcfg
Description
The armcfg command is used to manage LUNs (-L option) and physical disks
(-D option). LUN management includes creating and deleting LUNs. Disk
management involves adding, downing, and resetting disks.
Caution Deleting a LUN will delete all data on the LUN. Backup all vital
data on the LUN before deleting it.
Note If the LUN being deleted is very large, the time required to delete
the LUN may cause host I/O timeouts.
