5 SSE Alarms

Faults are reported separately for SSE cards, SSE disks, SSE groups, and partitions. See Table 8, Table 9, Table 10, and Table 11 for alarm descriptions.

You can configure the threshold for low-partition-space alarms using the following command in SSE partition configuration mode:

alarm low-partition-space raise-at raise_percentage clear-at clear_percentage

Verify card- and disk-level alarms using the show hardware slot detail command. Verify group- and partition-level alarms using the show sse group group_name detail command.

(1) Probable causes: a) The disk does not have enough space to create the partition; b) Another partition of the same name but with a different size already exists on the disk from a previous configuration. Solution: Use the delete partition command to free up disk space or remove the existing partition, or use the format sse command to remove all user-configured partitions on the disk. The format sse command can only be run on an SSE card that is not bound to any SSE group.
