Troubleshooting EVA4000 array connectivity 9–47
• There may have been a battery failure on the SFS20 array, causing the cache to be disabled.
See Section 8.1.12 for information about replacing a failed battery pack and cache on an SFS20
array.
9.28 Troubleshooting EVA4000 array connectivity
If you are encountering difficulties in accessing storage from an EVA4000 controller pair, make sure that
the presentations to your server are correct. The following three extracts from the
/var/log/messages
log file show the typical messages you might see if the storage is correctly
connected to the server.
Example 9-1 shows a log entry of the type created when the drivers are loading.

the
scsi: unknown type 12
message is normal.
