4.2 Array Problems
Many problems within an array are not seen by the users of the server. The RAID-1 and RAID-5 functions provide a continuing
service to the users even when a member of an array has failed. However, unless the failure is corrected, a second failure within
that array could cause the whole array to become unavailable. Therefore, it is very important that you check the error log for the
adapter regularly. You could do this by making such a check part of the startup procedure for your operating system.
If you are using OS/2, a pop-up window appears when an error is logged for the adapter or the disk drives attached to it. Also, the
pop-up window appears every hour while an error likely to affect the operation of the array remains on the log. The pop-up window
recommends that you check the entries in the error log.
To check the error log:
1. Start the configuration utility by executing the following program:
For OS/2: ISSACFG
For Novell NetWare: load ISSACFG
For Windows NT: ISSACFG
For DOS: ISSACFG
or, if it is available, double click on the SSA Configurator icon.
2. From the Main Menu, select Event/Error Logger and then Analyze SSA Event Log.
The current list of errors appears in a new window:

The SRNs (service request numbers) describe the errors.
Some SRNs describe errors with the adapter card or with the SSA configuration. These SRNs are listed in Appendix B, "SSA
RAID Adapter Service Request Numbers" in topic B.0 with a description of what you should do to solve the problem.
Some SRNs describe errors with the SSA disk drives or the units in which they are installed. For a complete description of
these, see the
Installation and User's Guide
or the
Maintenance Information
for that unit.
If one of the following SRNs appears, you can correct the problem by exchanging a disk drive for a new one:
Any SRN whose first character is '1'
60210
D0100
D0300
The following section describes what you need to do with the array configuration utility while changing a disk drive.
