4: Peripheral Use
For the SGI 1200 with hot-swap hard drives and the optional RAID controller, there are
two different methods to install new hard drives into a chassis with existing hard drives
already configured for RAID 5. The chassis must have a minimum of three hard drives
to support RAID 5. Both of these methods are summarized as B in Table 4-3. The first
method involves the following steps:
1. Back up your system.
2. Safely shut down the system.
3. Install the hard drive.
4. Configure the new hard drive in a fault tolerant configuration in a second volume.
5. Start the system.
6. Configure the drive as a new logical volume.
The second alternative involves the following steps:
1. Back up your system.
2. Safely shut down the system.
3. Install the hard drive.
4. Format hard drives to erase the old RAID 5 configuration.
5. Configure all the hard drives in the system as a RAID 5 as a single volume.
6. Start the system.
7. Restore your system files on the new drive configuration from backups.
