Object States and Substates
The storage subsystem supports these wild-card characters:
You can use wild-card characters in any combination. For example, this command
starts all disks whose name has D as the second character and the number 0 as the
sixth character:
-> START DISK $D???0*
Object States and Substates
The state and substate of an object provide current status information. Knowing the
object state and substate of an object can be critical. Some SCF commands have no
effect on an object when the object is in a particular object state and substate but can
affect the object when it is in another object state and substate. The substate further
defines why the object is in a particular object state. For example, when a disk is being
started, it might also need to be revived, which means it is in the STARTING state,
substate REVIVE. Not all objects have substates.
Object Attributes
The attributes for each object are described with the syntax of the ADD Command
(page 14-8).
* Represents a character string of undefined length. For example, to display the object
names of all disks managed by the storage subsystem:
-> NAMES DISK $*
? Represents a single unknown character in a specific position. For example, to start
disks named $DATA00, $DATA01, and so on:
-> START DISK $DATA0?
