Warning: Disk 1A does not match the installed disk.

The above message indicates that the S2A9550 does not recognize a disk that is part of a valid LUN
in the system. It may be in the wrong location or it may have been replaced without informing the
S2A9550. The data in the LUN’s will not be available until the original disk is restored or the disk is
marked as failed. Make sure the disk is installed correctly.

Warning: Internal parameter block 0 is invalid. Defaults loaded.

The above message indicates that the internal parameter block was invalid so the S2A9550 loaded a
default copy. This is a normal response when a S2A9550 is powered on for the first time. It will
attempt to get a valid copy of the parameter block from the disks. Saving the parameter blocks from
the terminal with the SAVE command will fix this error. If this error occurs after the system has been
configured properly then this may indicate that the parameter block has been corrupted, the
hardware is faulty, or there is a problem with the firmware.

Found older parameter block 0 on disk 1A.

Old Date: TUE MAY 02 11:18:58 2000

New Date: WED MAY 03 11:18:58 2000

The above message indicates that all the disk copies of this parameter block were older than the
internal copy of the parameter block. This usually occurs when the system is shut down before the
S2A9550 can save an updated parameter block to the disks. In this case the S2A9550 will correct the
problem the next time the parameters are saved. Saving the parameter blocks from the terminal with
the SAVE command will fix this error. This error may also occur if a new S2A9550 with a valid
configuration is attached to disks with a different configuration. In this case, disconnect the new
S2A9550 from the disks and use the DEFAULTS command to reset its settings and then reconnect it
to the disks. The new S2A9550 will then load the correct parameter blocks from the disks.

Loaded parameter block 0 from disk 1A.

Old Date: TUE MAY 02 11:18:58 2000

New Date: WED MAY 03 11:18:58 2000

The above message indicates that the internal copy of the parameter block did not match any of the
disk copies of the parameter block. The S2A9550 will load the latest copy of the parameter blocks
from the disks. In this case the S2A9550 will correct the problem the next time the parameters are
saved. Saving the parameter blocks from the terminal with the SAVE command will also fix this error.
This error may also occur if a new S2A9550 is attached to disks with a different configuration.

Fault: Parameter block error: %s is %ld should be %ld

The above message indicates that the S2A9550 detected a firmware incompatibility error. This
indicates a problem with the firmware. The S2A9550 may not function correctly after this type of
error.

Do not use the

S2A9550

in this state or the system may become permanently corrupted

. Downgrade

the firmware in the S2A9550 to a previous version known to be stable.

Warning: Error saving parameters, Invalid block 0

The above message indicates that the S2A9550 has detected an internal firmware error. The S2A9550
may not function correctly after this type of error and data may have been lost. This indicates a
problem with the firmware. Downgrade the firmware in the S2A9550 to a previous version known to
be stable.
