ResolutionCheck Hitachi SAN interface to see if the LUN is write protected or data protected.
Root Cause
Error "Data Protect" is described as:
Indicates that a command that reads or writes the medium was attempted on a block that is protected from this operation. The read or write operation is not performed.
Diagnostic Steps
Attempt to mount the ext3 filesystem (produces error above).
Attempt to write an EXT2/3 Label to the EXT3 filesystem on the Logical Volume (also produces the above area)
Consult Hitachi support to see if the SAN LUN is write/data protected.
