1.5 RACADM Commands for Configuring Physical Disk Drives (Pdisk)
There are a set of physical disk drive configaration commands to perform operations such as assign or
unassign hot-spares, force online/offline, and rebuild after a physical disk drive failure. The physical disk
drives must be set to RAID–capable mode before creating a virtual disk. Converting to RAID–capable and
non-RAID―capable can be done using RACADM commands as discussed here.
$ racadm raid converttoraid:<PD FQDD>
$ racadm raid converttononraid:<PD FQDD>
A hot-spare, that is, a spare hot-swappable physical disk drive for a particular virtual disk can be configured
running the RACADM command:
$ racadm raid hotspare:<PD FQDD> -assign yes -type ghs
The –type switch to indicate the type of hot-spare. That is, ghs (global hot-spare) or dhs (dedicated hot-
spare).
$ racadm raid hotspare:<PD FQDD> -assign yes
-type dhs -vdkey:<VD FQDD> to indicate dhs()—dedicated hotspare and the existing command
indicates ghs(global hot spare)
The hot-spare configuration of a physical disk drive can deleted by running the RACADM command:
$ racadm raid hotspare:<PD FQDD> -assign no
1.6 Storage Configuration Commands
Storage config commands are used to monitor or configure storage attributes. It supports the
configuration of controller, physical disk drives, and virtual disks configurations using the RACADM get
and set mechanism.
Controller commands
The command examples are:
1. To list all the available controllers:
$ racadm get storage.controller.
RAID.controller.1 [Key=RAID.Integrated.1-1#Controller]
2. To list all the supported attributes of controller 1
$ racadm get storage.controller.1.
