To increase: You can:
Application performance Increase the number of member systems.
I/O performance Increase the number of shared buses.
Member system availability Increase the number of member systems.
Cluster interconnect availability Use redundant cluster interconnects.
Disk availability Mirror disks across shared buses.
Use a RAID array controller.
Shared storage capacity Increase the number of shared buses.
Use a RAID array controller.
Increase disk size.
4.2 Obtaining the Firmware Release Notes
You may be required to update the system or SCSI controller firmware
during a TruCluster Server installation, so you may need the firmware
release notes.
You can obtain the firmware release notes from:
• The Web at the following URL: http://www.compaq.com/support/
Select software & drivers, then select AlphaServer under the
servers heading. Select the appropriate system.
• The current Alpha Systems Firmware Update CD-ROM.
_____________________ Note _____________________
To obtain the firmware release notes from the Firmware
Update Utility CD-ROM, your kernel must be configured for
the ISO 9660 Compact Disk File System (CDFS).
To obtain the release notes for the firmware update, follow these steps:
1. At the console prompt, or using the system startup log if the Tru64
UNIX operating system is running, determine the drive number of
the CD-ROM.
2. Boot the Tru64 UNIX operating system if it is not already running.
3. Log in as root.
4. Place the Alpha Systems Firmware Update CD-ROM for the
installed (or to be installed) Tru64 UNIX version into the drive.
