Receiving "sense key Data Protect" errors when trying to mount EXT3 filesystem from SAN device on Red Hat Enterprise Linux

Solution Verified - Updated -


  • Volume group on SAN disk is activated. When I try to mount ext3 filesystem on LVM logical volume, we get the following error in /var/log/messages:
kernel: SCSI error : 3 0 0 0> return code = 0x8000002
kernel: Current sda: sense key Data Protect
kernel: Additional sense: Illegal function (use 20 00, 24 00, or 26 00)
kernel: end_request: I/O error, dev sda, sector 602496
kernel: device-mapper: dm-multipath: Failing path 8:0.
kernel: end_request: I/O error, dev sda, sector 602504
  • LVM mirroring issue. We are not even able to create the PV on the new disks.

Getting below error.

$ pvcreate <device-path>
