dac960sh --
dac960 system administration shell utility
Syntax
dac960sh
Description
dac960sh is a semi-graphical front-end shell administration
utility for administering the DAC960 adapters.
The options in the menu are:
select DAC
Up to four DAC960s are supported in a system.
This option allows you to select an adapter. Adapters are
numbered 1 through 4. The adapter seated in the LOWEST slot
is Adapter #1.
rebuild
Rebuilds the physical devices and sets them online. This option allows you
to rebuild a disk drive, and should be used after replacing a ``dead''
disk drive. The new disk must have the same Target ID as that which
it has replaced. This option first formats the disk. (If this disk has
been previously formatted on a DAC960, you may choose to bypass
the formatting option while invoking rebuild.) After
formatting the disk, a rebuild is initiated on the DAC960.
All system drives dependent on this disk are brought back to consistency,
and progress of the rebuild is reported. If bad sections are found on the
system drives, those sections cannot be rebuilt; however the rebuild
still gives you the option of bringing the new disk Online.
Bad-Blocks are logged in the file /usr/adm/dac960rbld.
change device
Enables you to change device. This option stops the channel before
the change, and starts the channel when the change is complete.
When replacing a ``dead'' disk drive, all disk activity on the
SCSI bus on which a drive must be replaced is shut down.
A warning message is
first broadcast to all users. You must then power off the ``dead''
disk and
disconnect the SCSI cable. You may then exit the utility by typing
resume which restores the normal activity of the system. When a new
disk is installed, you should first set the SCSI ID to the
ID of the
dead disk. Invoke change device, then connect the SCSI
cable to the disk,
power on the new device, and then exit change device. Allow the
disk to spin-up for approximately 30 seconds, then invoke the rebuild utility.
DAC90 toolkit
This option allows the user to issue miscellaneous low level commands to
DAC960. The menu executes the dac960tk utility.
quit
This option takes you out of DAC960 administrator's shell. The screen
is cleared and cursor is set to the bottom line.
Known limitations
If you select DAC960 toolkit from the menu, the menu that is then
displayed is identical to that which is displayed when you run
dac960tk, however you will be unable to choose the
select next option. To choose select next, you must
run dac960tk from the command line.
