Performing RAID maintenance Standard 1.0
234 CallPilot
Splitting DAC960 RAID drives and
upgrading software
Introduction
Use this procedure on a CallPilot server that is configured with a DAC960
RAID controller. This procedure breaks the mirroring of the hard drives
before an upgrade so that if the upgrade fails, you can quickly return the
server to the state it was in before you started the upgrade.
There are three stages to this procedure:
1. Preparing the CallPilot server for the upgrade
2. Performing the CallPilot server software upgrade
3. Resynchronizing the CallPilot server hard drives
Requirements
As a precaution, ensure that you have a full system tape backup
available.
You need to have either the CallPilot 2.0 OS Recovery CD or the
CallPilot 2.0 OS Upgrade CD
You need a blank 3.5 inch, 1.44 Mbytes formatted floppy disk to use to
back up the RAID configuration.
The server must have a standard hard drive configuration as documented
in “RAID system pack locations and identifications” on page 237.
