Unowned LUN's

[Deepak Majumdar]

Hi All,

We have a Clariion 5400 with DPE and one DAE with 10 disks each and is connected to brocade silkworm 2800 FC switch. We have defined two LUNS for two different servers.

Due to dirty cache, one of the LUN (lun00) has got moved to "UNOWNED" LUN group and is not owned by neither the active nor the passive SPA's.

We have rebooted the clariion several times and in the LOG messgaes of the storage box it shows

"Enclosure 0 disk 0 : Cache Dirty"

How can we bring it back to original state. The entire research data is on this LUN. We have no backup for that particular LUN.

Kindly helpus in resolving the issue and also let me know the procedure for doing the same.

Thanks & Rgds,

Deepak
