3.2.1 Troubleshooting the DECarray

The following sections describe the procedure for isolating a fault or

failure in the DECarray.

3.2.1.1 Introduction

The DECarray consists of a power controller to supply ac power for

internally installed storage enclosures, a 16-port I/O panel to connect the

DECarray to a system or systems, and the DECarray cabinet assembly.
The DECarray also consists of three DSSI cables; the 108-inch cable (PN

BC21Q–09 or BC22Q–09), that connects the DECarray to the system(s),

the 70-inch cable (PN BC21R–5L), that connects the storage enclosure

to the DECarray I/O panel, and the 42-inch cable (PN BC21Q–3F) that

connects the storage enclosure to another enclosure.

3.2.1.2 Configuration Verification

Use this section only after you have determined that the problem or fault

not

in the adapter modules or tape magazine tape ISEs.

1. Check that the DECarray has been configured according to the

DECarray Installation Guide

2. Ensure that all ISEs in the storage enclosures have the correct DSSI

switch settings, and that each ISE on each DSSI bus has a unique

DSSI node ID for that bus.

3. Ensure that the KFMSA adapter(s) in the systems are set correctly.
4. If the DECarray contains magazine tape ISE(s) in single-system or

DSSI VAXcluster configurations, ensure that it has a unique DSSI

node ID. See the magazine tape documentation for instructions on

how to check and change the node DSSI ID.

If the problems persist, record the symptoms and consult Section 3.3.
