There is S5000VSA board configured ad ESRT2 RAID. 3VDs - 2 raid 1 and 1 - raid 0. OS - W2008 R2, latest storage drivers and rwc2.
first VD contains OS and act as Hyper-V Server, second VD contains vhd files of virtual machines and third VD (raid 0) is used as a backup drive.
There is event 113 registering every several seconds in rwc.
|113||[Information, 0]||2013-05-23, 21:04:05||Controller ID: 0 Unexpected sense: PD = -:-:2No addtional sense information, CDB = 0x28 0x00 0x01 0x9d 0x8c 0x00 0x00 0x00 0x14 0x00 , Sense = 0x70 0x00 0x03 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x80 0x00 0x02||878|
According to alert decoding document CDB 0x28 means READ command was sent. 2-nd sense byte 0x03 means medium error but Additional Sense Code and Additional Sense Code Qualifier both 0x00 which doesn't correspond to any particular error. During this errors the system is mostly unresponsive and VD with raid 0 (disk F: in OS) cannot be accessed. Although rwc2 says that raid status is optimal and all drives are online.
But simple soft reset rescues all this for about a day, then event 113 appears once agains and so on. Any thoughts ?
