Troubleshooting Table 6-14 Most Common Microcode Panic Codes (Continued) Value Description 0x00000015 0x00000016 Memory exhausted. Memory exhausted. 0x00100006 Degraded LUN experiencing heavy I/O. Reported on a very large, degraded RAID-5 LUN (usually with more than eight disks) under heavy I/O conditions. Fixed in microcode revision 8.09. 0x00100017 0x00220011 Multiple trespasses. Could be caused by multiple trespasses taking place during a rebuild. The trespass disabled the SP, which caused the rebuild to abort. After this happens several times, the array panics. Avoid trespass during a rebuild. Fixed in microcode revisions 9.53 and 9.23. Cache dump conflicts with trespass. If a write cache fault dump conflicted with an attempted trespass of a "dirty" unit, the microcode would intermittently panic with a 0x00220011. Fixed in microcode revision 8.20. 0x00220013 0x00220023 0x00220026 0x00220030 Alternating LUN assignment with cache and auto-trespass enabled. If the host continuously alternates assignment of a LUN between peer SPs, the microcode would panic with 0x00220013. This would only happen if cache and auto-trespass were enabled. Fixed in microcode revision 7.61 Memory or resource panic. Normally occurred during large file I/Os. Fixed in microcode revision 9.07. Memory or resource panic. Occurred while LUNs were continuously trespassed under a heavy I/O load. Fixed in microcode revision 8.15. Unexpected lock. The execution of a disk read/write operation detected an invalid conflict with another operation. 0x00220032 0x00220040 Cache page processing. Executing large block reads (>64 KB) could result in this panic when a SCSI front end process attempts to process a cache page. Fixed in microcode revision 7.16. Inter-process communication panic. Occurred when taking an error while trying to respond to a request from a host. Fixed in microcode revisions 8.27, 8.58, and 9.04. 0x00220050 0x00220054 0x00220055 I/O panic. The microcode panics 0x00A000B0, 0x00240010, and 0x00220050 occurred in SCSI environments that had severe SCSI protocol problems due to malfunctioning initiators or noisy conditions. Fixed in microcode revisions 8.27, 8.58, and 9.04. I/O panic. Caused by issuing a SCSI Write Verify command several times under certain conditions. Fixed in microcode revision 7.61. I/O panic. Executing a SCSI Verify or Write Same commands to a Fast RAID-3 LUN would result in 0x00280002 or 0x00220055 panics. Fixed in microcode revision 9.09. Unsolicited Event Log 6-57
