Hard Drive Upgrade Strategies
This section provides information about hard drive upgrade strategies for SGI 1200
servers with RAID and non-RAID drives. The SGI 1200 server can be configured with up
to four internal hard disk drives.
Note: When upgrading storage, the system must be powered down to install the new
drives, regardless of the drive type or RAID controller being used.
Caution: Always perform a full backup before upgrading your SGI 1200 server.
To install internal hard drives perform the following steps:
1. Back up your system.
2. Safely shut down the system.
3. Install the hard drive.
4. Restart the operating system.
5. Configure the new device as applicable to your operating system.
The two independent SCSI channels on the motherboard enable a variety of external
SCSI connections. Table 4-1 shows that the SGI 1200 server can be connected to Ultra
SCSI by way of an optional SCSI connector, and some versions can connect with an
Ultra2 connection.
Table 4-2 describes some of the internal and external RAID upgrade parameters for the
SGI 1200 chassis with midplane and optional RAID controller.
