START is a sensitive command.
START DISK Command
The START DISK command makes a stopped disk accessible to user processes. If needed, this
command also revives the half of a mirrored volume that is in the STOPPED state, substate DOWN.
The syntax is:
START [ / OUT file-spec / ] DISK $disk [-P |-B |-M |-MB ]
[ , DEBUG $terminal ] [ , POOL $pool ]
[ , SEL state ] [ , SPECIAL ]
[ , SUB { ALL | MAGNETIC | VIRTUAL } ]
Wild-card characters are supported.
OUT file-spec
directs all SCF output to the specified file.
DISK $disk[-P |-B |-M |-MB ]
is the disk name and, optionally, the path (primary, backup, mirror, or mirror backup).
DEBUG $terminal
specifies that the process should start in debug mode on $terminal.
POOL $pool
specifies that the command is performed only on disks associated with the specified storage
pool.
SEL state
specifies that the command affects only devices in the specified state.
SPECIAL
puts the disk into the SERVICING state, substate SPECIAL. Use this attribute to ensure that only
privileged processes can access the disk. You must designate the entire primary or mirror path.
SUB { ALL | MAGNETIC | VIRTUAL }
specifies that the command affects only disks of the specified type. The default is ALL.
See “Attribute Descriptions for Disk Commands” (page 198) for descriptions of all attributes for disk
commands.
START DISK Examples For Physical Disks
See the procedure for “Starting a Disk” (page 97) and the procedure for “Starting a Virtual Disk”
(page 150).
• To start all disks on the system (that are in the proper state to start):
-> START DISK $*
• To start a mirrored volume:
-> START $DATA00-M
• To start a disk and put it in the SERVICING state, substate SPECIAL:
-> START $DATA03, SPECIAL
• To start all available virtual disks:
-> START DISK $*, SUB VIRTUAL
