iscsi drive refuses to mount

[proactis]

I have a iscsi drive that tells me that the extents are missing and cannot be remounted, esxi see's the drive in vclient but when I try and add as storage  i receive the following errors

When I try resignature it I get this

Resignature unresolved VMFS volume
192.168.1.180
Error during the configuration of the host: Unable to resignature this VMFS3 volume due to some extents missing

When I try and keep the signature it then pops up a box with the following message

Cannot change the host configuration

Is this a single LUN datastore, or was the datastore made up of LUN extents?

Its a single LUN

[kjb007]

If it's a single LUN, then you may have problems on the iSCSI side.  Have you verified you're not having hardware problems on the iSCSI target with respect to disk?

I have another LUN that attaches to the same SAN on the same VMWare box and that has no issues so I don't believe that there is the issue.

[kjb007]

Is that 2nd LUN using the same underlying hard disk?

Yes it is, the disk has numerous other hosts connecting to the same disk too
