Hi,
It also could be a referenced EMC bug on Linux. Regarding to the OS version
(RHEL3) and the LVM usage or not, all LUN are not clearely presented to the host
via PowerPath. If this is your case, remove LVM or remove PowerPath or patch LVM
yourself but you will lose support.
Regard.

define.. unreadable.
Is the disk mounting? I assume not. What are the errors?
Also, is this snapshot writable? As in, can a process write to this
snapshot volume.
Considering we do heartbeat on the disk itself, wondering if that is the
cause of the
error.
