40 Critical The sensors monitored a temperature or
voltage in the failure range.
• Check that the storage system’s fans are
running.
• Check that the ambient temperature is not
too warm. The enclosure operating range
is 41–104° F (5–40° C).
• Check for any obstructions to the airflow.
• If none of the above explanations apply,
replace the controller FRU that reported
the error.
When the problem is fixed, event 47 is
logged.
41 Informational A vdisk spare has been added.
43 Informational A vdisk has been deleted.
44 Warning The controller contains dirty cache data for
the specified volume but the corresponding
disks are not online.
• Determine the reason that the disks are
not online.
• If an enclosure is down, determine
corrective action.
• If the vdisk is no longer needed, you can
clear the orphan data; this will result in
lost data.
45 Informational A communication failure has occurred
between the controller and an EMP.
47 Informational An error detected by the sensors has been
cleared.
48 Informational The vdisk name has been changed.
49 Informational A lengthy SCSI maintenance command has
completed.
52 Informational Vdisk expansion has started. This operation can take days to complete.
53 Informational
or warning
This event is logged as informational when a
vdisk expansion has completed or a RAID
morph operation is canceled by the user. This
event is logged as a warning if the RAID
morph operation fails.
55 Informational A SMART event occurred on the specified
disk.
Impending disk failure. See Table 15.
56 Informational The SC has been restarted.
58 Warning or
informational
A disk or other SCSI device (such as an EMP)
detected an error. This event is logged as a
warning for serious errors such as parity or
disk hardware failure, and as informational
for other errors.
• For warning events that indicate a disk is
bad, replace that disk.
• For warning events that indicate an
expansion module is bad, replace that
expansion module.
59 Warning or
informational
The controller detected an error while
communicating with the specified SCSI
device. The error was detected by the
controller, not the disk. This event is logged
as a warning for parity errors, and as
informational for other errors.
• For warning events that indicate a disk is
bad, replace that disk.
• For warning events that indicate an
expansion module is bad, replace that
expansion module.
