Table 28. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
Recommended actions:
● Replace the disk with one of the same type (SSD, enterprise SAS, or midline SAS) and the
same or greater capacity. For continued optimum I/O performance, the replacement disk
should have performance that is the same as or better than the one it is replacing.
322 Warning The controller has an older Storage Controller (SC) version than the version used to create the
CHAP authentication database in the controller’s flash memory.
The CHAP database cannot be read or updated. However, new records can be added, which will
replace the existing database with a new database using the latest known version number.
Recommended actions:
● Upgrade the controller firmware to a version whose SC is compatible with the indicated
database version.
○ If no records were added, the database becomes accessible and remains intact.
○ If records were added, the database becomes accessible but contains only the new
records.
352 Info. Expander Controller (EC) assert data or stack-dump data are available.
Recommended actions:
● No action is required.
353 Info. Expander Controller (EC) assert data and stack-dump data have been cleared.
Recommended actions:
● No action is required.
354 Warning SAS topology has changed on a host port. At least one PHY has gone down. For example, the
SAS cable connecting a controller host port to a host has been disconnected.
Recommended actions:
● Check the cable connection between the indicated port and the host.
● Monitor the log to see if the problem persists.
Info. SAS topology has changed on a host port. At least one PHY has become active. For example,
the SAS cable connecting a controller host port to a host has been connected.
Recommended actions:
● No action is required.
355 Warning The debug button on the faceplate was stuck on during boot up.
Recommended actions:
● If the button remains stuck, replace the controller module.
356 Warning This event can only result from tests that are run in the manufacturing environment.
Recommended actions:
● Follow the manufacturing process.
357 Warning This event can only result from tests that are run in the manufacturing environment.
Recommended actions:
● Follow the manufacturing process.
358 Critical All PHYs are down for the indicated disk channel. The system is degraded and is not fault
tolerant because all disks are in a single-ported state.
NOTE: ME5 Series systems support only dual-ported disks.
Recommended actions:
● Turn off the power for the controller enclosure, wait a few seconds, and turn it back on.
