Compaq AA-RHGWC-TE manual Cluster Administration

Your storage shelves or RAID array subsystems should be set up before completing this portion of an installation.

Use the steps in Table 4–3 to set up a KZPBA-CB for a TruCluster Server cluster that uses radial connection to a DWZZH UltraSCSI hub.

Table 4–3: Installing the KZPBA-CB for Radial Connection to a DWZZH UltraSCSI Hub

Step	Action	Refer to:
1	Ensure that the eight KZPBA-CB internal	Section 4.3.1, Figure 4–1,

termination resistor SIPs, RM1-RM8 are installed. and KZPBA-CBPCI-to-Ultra SCSI Differential Host Adapter User’s Guide

Power down the system. Install a KZPBA-CB	TruCluster Server
PCI-to-UltraSCSI differential host adapter in	Cluster Administration,
the PCI slot corresponding to the logical bus to	Section 2.3.3, and
be used for the shared SCSI bus. Ensure that	KZPBA-CB PCI-to-Ultra
the number of adapters are within limits for the	SCSI Differential Host
system, and that the placement is acceptable.	Adapter User’s Guide
Install a BN38C cable between the KZPBA-CB	—
UltraSCSI host adapter and a DWZZH port.

_____________________ Notes _____________________

The maximum length of a SCSI bus segment is 25 meters, including the bus length internal to the adapter and storage devices.

One end of the BN38C cable is 68-pin high density. The other end is 68-pin VHDCI. The DWZZH accepts the 68-pin VHDCI connector. The number of member systems in the cluster has to be one less than the number of DWZZH ports.

4Power up the system and use the show config and show device console commands to display the installed devices and information about the KZPBA-CBs on the AlphaServer systems. Look for QLogic ISP1020 in the show config display and isp in the show device display to determine which devices are KZPBA-CBs.

Section 4.3.2 and Example 4–1 through Example 4–4

5Use the show pk* or show isp* console commands to determine the KZPBA-CB SCSI bus ID, and then use the set console command to set the SCSI bus ID.
