-> STOP DISK $DATA1-M
-> STOP DISK $DATA1-MB
-> DELETE DISK $DATA1-M
NOTE: Allow 20 seconds to ensure the DELETE DISK command completes before proceeding
to the ALTER DISK command in the next step. When using a TACL obey file or SCF infile, put
the DELETE DISK commands in a different obey file or infile from the ALTER command.
6. Then issue an ALTER DISK $disk-volume-name command whose MIRRORLOCATON
attribute assigns the mirror disk drive, which was once the primary disk drive, to location
(1,1,1):
-> ALTER $DATA1, MIRRORLOCATION (1,1,1)
A prompt then gives you the option of reviving the disk drive.
NOTE: When using SCF with an infile, SCF will start reviving if the disk is already initialized.
Use the attribute NOSTART with the ALTER DISK command to specify that the configured mirror
disk should not be started.
7. To return both disk drives to their original roles, use the SWAPMIRROR attribute again:
-> ALTER DISK $DATA1, SWAPMIRROR
Adding a Disk
The “ADD DISK Command” (page 194) adds one or more disks to the system configuration database.
• You can insert the disk before or after entering the ADD command, unless you are adding the
first disk in an M8xxx FCDM daisy chain.
• For daisy-chained M8xxx FCDMs, there must be at least one disk somewhere in the daisy
chain, so that the storage subsystem can verify that the two paths specified in the ADD
command go to the same daisy chain.
• For internal disks, if AUTOCONFIGURATION and AUTOSTART are on, the disk process
automatically starts when you insert the disk. If AUTOCONFIGURATION and AUTOSTART
are off, insert the disk and then enter the ADD command. For more information, see
“Automating Disk Configuration” (page 73).
NOTE: HP does not recommend AUTOCONFIGURATION for M8xxx disks.
• New M8xxx disks that are being used for the first time must be initialized after they have
been added.
• When automatic configuration is enabled, internal disks are automatically added and optionally
started. You do not need to enter an ADD command.
Steps to Add a Disk
Use this procedure for internal disks if autoconfiguration is not enabled.
1. For the PRIMARYLOCATION attribute, note the group, module, and slot location where you
install the disk.
2. Add the disk:
-> ADD DISK $DATA02, SENDTO STORAGE, PRIMARYLOCATION (1,1,3)
3. Verify the attributes recorded in the system configuration database:
-> INFO $DATA02, DETAIL
4. See “Starting a Disk” (page 97).
