Restoring a mirrored system from a CMSADM backup 3
This section shows you how to restore an entire mirrored system from a
CMSADM backup. You might have to do this procedure, for example, if
you have a disk crash that disables the operating system disk drive.
To do this procedure, you will need the “
Solaris
7 3/99” compact disc and
the most recent CMSADM backup tape. You will also need to know your
system’s host name, host ID, and IP address.
Step 1: Power off
the system

Power off the system by doing the following tasks:
1. Turn off the system unit.
2. Turn off the system monitor.
3. Turn off all external devices starting with the device closest to the
system unit and working toward the farthest device.
Step 2: Install the
new drives

You must wear an ESD wrist strap when installing or removing hard disk
drives to prevent electrical discharge that may harm system components.
In Sun Enterprise 3xxx systems, the internal hard disk drives install in the
front of the system. To expose the disk drive bays, open the front access
door.
Each disk drive has a retainer latch/drive handle on the front of the drive.
To install a drive, unlatch and extend the retainer and slide the drive
carefully into the appropriate drive slot. When the drive stops, gently
apply pressure to the face of the drive until you hear the connectors
engage. Then lower the retainer latch and snap it in place, making certain
the drive is secure and does not extend beyond the front of the chassis.
Do not use excessive force to seat the connector or to close the retainer
latch.
For additional information about hard disks and disk drives, see the
Sun
System Reference Manual
appropriate to your hardware platform.
