● To continue using the feature after the trial period, purchase a permanent license.
317 Error A serious error has been detected on the Storage Controller disk interface. The controller will be
killed by its partner.
Recommended actions:
● Visually trace the cabling between the controller modules and expansion modules.
● If the cabling is OK, replace the controller module that logged this event.
● If the problem recurs, replace the expansion module that is connected to the controller
module.
319 Warning The indicated available disk has failed.
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.
356 Warning This event can only result from tests that are run in the manufacturing environment.
Recommended actions:
