Troubleshooting Table 6-8 Informational Codes (Continued) Event code Event code name Description 0x645 CRU Bound 0x646 CRU Unbound 0x647 Fuse Bad Extended status identifies unit number. This message is logged once for each CRU in a LUN at the completion of a Bind operation. Extended status identifies unit number. This message is logged once for each CRU in a LUN at the completion of an Unbind. Extended status identifies fuse number. This message is logged once at the completion of each powerup for any bad fuse detected by the SP. 0x648 0x650 0x654 0x657 0x658 Termpower Low Extended status identifies SCSI bus number. This message is logged once at the completion of each powerup for any SCSI bus which the SP detects as having an insufficient "TERMPWR" voltage level. This event code is only used by SPs that do not themselves source termpower into the bus (for example, Telmo). FRU Signature Error The given FRU's current physical position in the disk array chassis does not match its expected position (which is set at the time the FRU is bound into a LUN). Cache Dumping The SP started dumping the storage system cache data to the cache vault disks. Cache Dump Completed The SP finished dumping the storage system cache to the cache vault disks. Cache Enabling The SP is in the process of enabling the cache for use on host data. 0x659 Cache Disabling 0x660 AC Power Fail Storage-system caching was disabled by the disk array or system operator. The disk array disables caching if the BBU is not fully charged or an SP, cache vault disk or fan fails; see error 0x908. After an AC power failure, the disk array dumped the cache to the vault and turned off power to the BBU (to minimize drain on the BBU). 0x661 0x662 BBU Sniffing Enabled BBU Sniffing Disabled The disk array is allowed to shut down the BBU in order to test it. BBU shutdown testing is disabled on this disk array. 0x663 0x664 0x665 BBU Sniff Initiating The BBU is beginning a shutdown test cycle. BBU Sniff Cache Dump In preparation for its weekly BBU test cycle, the disk array dumped its cache data. This message is followed by a 0x663 message. Configured for Single SP The disk array detected a change to a single SP configuration. Unsolicited Event Log 6-41
