CX3-20 CRU Powered Down
I got several alarms last night from a customers CX3-20 with this text:
Time Stamp 10/30/09 02:49:20 Event Number a07 Severity Critical Error Host EMC_CX3B Storage Array CKXXXXXXXXX145 SPB Device Enclosure 3 Disk 0 Description CRU Powered Down
The same repeated for all disks at every enclosure.
First question: What is the CRU?
Second Question: Is this an informative alarm, or an actual failure?
The array is working properly, no fault log was collected, no physicall issues, and the systems administrator said that no performance issues nor host failure was detected.
Ideas?

First question: What is the CRU?
CRU: Customer Replacable Unit,(mostly a disk, since the location is for the disk...Enclosure 3 Disk 0 )
Second Question: Is this an informative alarm, or an actual failure?
A07: is always a disk failure indication
I will take this seriously as this is occuring on all fist drives of enclosure...
Mostly a fault with the Bus or SP/calbe rather than all the frist drives..
Might be the port is going up/down ... we call this a loop issue
Please log a call to EMC ASAP!!! as this is nota fake error as the date is also current one....

Vivek

EMC verified that the power supply is working normally, and everything seems to be all right. The client still wonders what happend, but nobody can give an explanation. We asked EMC to replace the powersupply proactively just in case.
