EMC AX100SC Release Notes - Page 10

Fixed Problems Problem AX100SC, AX100SCi, AX100, AX100i. One or more virtual disks and RAID Groups disappear after an SP reboots. (119661, 119105, 117351, 117665, 118887, 121446) AX100SC, AX100SCi, AX100, AX100i. Unbinding a virtual disk while hot spares are swapped in will cause CRU signature errors. (121545, 121069, 122843) Detail Fixed in Release: 02.17.xxx.5.006 Solution: This happened only after a RAID Group create failed. One or more virtual disks and RAID Groups on the same disks could disappear after an SP rebooted. Fixed the code to clean up properly after the failed RAID Group creation to avoid the problem. Fixed in Release: 02.17.xxx.5.006 Solution: The unbind code invalidates all CRU partition signatures. This was causing the hot spare's CRU signature to be corrupted. Changed the code to invalidate only CRUs that do not have a hot spare swapped in so the corruption does not occur. Also added a check in the unbind code to determine if the virtual disk is rebuilding to a hot spare and return an error if it is. 10 EMC AX100-Series Integrated Management Software Release Notes
