Array Problems
Array Problems
Many problems within an array are not seen by the users of the
server. The RAID-1 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 start-up
procedure for your operating system. If an array is attached to a cluster
of servers, all errors in the array are logged to both servers.
Errors that occur during configuration might not be logged to both servers.
To check the error log:
- Start the configuration utility by executing the program ISSACFG
or, if it is available, double click on the SSA Configurator icon.
- From the Main Menu, select EvenVError 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,
'SSA RAID Cluster Adapter Service Request Numbers'
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.
