Warning: SDRAM Cache size is invalid.
The S2A9550 tried to initialize the cache descriptors and found that the size reported for the SDRAM
was invalid. This error will prevent the system from running normally. Make sure the SDRAM is
installed correctly.
Warning: Cache descriptor allocation is full.
The S2A9550 tried to initialize the cache descriptors and ran out of memory. The S2A9550 will
continue to function normally but will be unable to use all of the SDRAM in the system for caching.
This error should only occur if an extremely large amount of SDRAM cache is installed in the system
and the cache cluster size is set very small. This can be corrected by increasing the cache cluster size
of the unit.
Warning: Cluster size is invalid. Restoring saved value.
The S2A9550 tried to initialize the cache descriptors and found that the cache cluster size to be used
was invalid. The S2A9550 will load the saved value from the parameter blocks and continue. It should
continue to run normally but the cluster size may need to be adjusted. This may indicate a problem
with the firmware.
Warning: Cluster size is invalid. Restoring default value.
The S2A9550 tried to initialize the cache descriptors and found that the cache cluster size to be used
was invalid. The S2A9550 also found the saved value in the parameter block to be invalid as well. It
will load the default value and continue. This unit should continue to run normally but the cluster size
may need to be adjusted. This may indicate that the parameter block has been corrupted.
4.2.6 Disk Boot-up Error Messages
Warning: Unexpected Disk interrupt channel:A status: msg:
Warning: Unexpected Host interrupt port:1 status: msg:
The S2A9550 received an interrupt from the host port or disk channel that it was not expecting. This
may indicate a problem with the firmware or hardware.
Waiting for disks to Boot: 3FF
The S2A9550 sent a request to the disk channels to perform a LIP and to report the results back. This
message indicates that the LIP request is taking a long time and the S2A9550 is still waiting. The LIP
results will be delayed if a disk is in the process of spinning up. It is normal for the disks to take a
while to boot when the unit is first powered on. The hex number at the end of the message is a bitmap
that indicates which disk channels the unit is still waiting for. This message is informational only.
Warning: Disk boot incomplete: 3FF
The S2A9550 sent a request to the disk channels to perform a LIP and to report the results back. This
message indicates that the LIP request took too long and at least one disk channel failed to report in.
The hex number at the end of the message is a bitmap that indicates which disk channels failed to
report in. This error will prevent the system from running normally. This may indicate a problem with
the hardware or the disks in the array.
Warning: Disk channel A boot failure.
The above message indicates that a disk channel failed to boot properly. This error will prevent the
system from running normally. This may indicate a problem with the hardware.
