SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

-> ALTER $ZZSTO, AUTOCONFIG ON
The storage subsystem looks for a custom profile (see “Creating a Custom Profile” (page 75))
for the enclosure. If no custom profile exists, the storage subsystem uses the default profile (see
“Example of an INFO PROFILE Report” (page 54)) to configure the disk.
To make internal disk configuration plug and play, enable these attributes:
-> ALTER $ZZSTO, AUTOCONFIG ON, AUTOREVIVE ON, AUTOSTART ON
3. After configuring the disk, the storage subsystem checks the disk label:
• If the disk is not labeled and AUTOLABEL for $ZZSTO is ON, it labels the disk.
• If the disk is not labeled and AUTOLABEL for $ZZSTO is OFF, see “Naming a Disk”
(page 88).
4. If AUTOSTART for $ZZSTO and the disk is ON, it starts the disk process. If AUTOSTART is
OFF for either $ZZSTO or the disk, see “Starting a Disk” (page 97).
5. If the disk is mirrored and all of these statements are true, a revive is started from the already
installed disk to the just inserted disk:
• AUTOREVIVE for $ZZSTO is ON.
• The slot is already configured as the mirror of an installed disk.
• Both disks are physically present.
Configuring Internal Disks to Start Automatically
NOTE: HP does not recommend using AUTOSTART with M8xxx Fibre Channel disks.
The AUTOSTART attribute affects the start behavior of internal disks differently depending on the
object type specified:
• AUTOSTART for the SUBSYS object type:
-> ALTER SUBSYS $ZZSTO, AUTOSTART ON
For the storage subsystem, the AUTOSTART attribute controls whether disks are automatically
started after disk insertion. AUTOSTART for the SUBSYS overrides AUTOSTART for the PROFILE.
• AUTOSTART for the DISK object type:
-> ALTER DISK $DISK1, AUTOSTART ON
For an individual disk, the AUTOSTART attribute controls whether a disk is automatically started
after system load, processor reload, or disk insertion.
These attributes interact as follows:
DISK AUTOSTART OFFDISK AUTOSTART ON
Disk automatically starts after:Disk automatically starts after:SUBSYS AUTOSTART ON
◦ System load No◦ System load Yes
◦ ◦Disk insertion Yes Disk insertion No
Disk automatically starts after:Disk automatically starts after:SUBSYS AUTOSTART OFF
◦ System load No◦ System load Yes
◦ ◦Disk insertion No Disk insertion No
