Direct link to the package listing is: http://atrpms.net/dist/el5/iscsitarget/.

The scsi-target-utils package distributed with RHEL/CentOS 5.3 is okay for simple stuff, but definitely out of date. And it completely fails when attempting to boot diskless systems via iSCSI over Infiniband. Spent quite a bit of time tonight attempting to figure out why BoIB 2.0.0 with a ConnectX card refused to communicate with my apparently working (export connectable/useable on other machines) iSCSI volume. Replaced tgtadm with the enterprise iSCSI target, and boom – instant satisfaction.

YMMV.

Set new UUID on XFS Partition, RHEL/CentOS:

xfs admin -U generate /dev/sdb1

Set new UUID on XFS Partition, SLES/OpenSUSE:

xfs_admin -U generate /dev/sdb1

Set new UUID on ext3 Partition and Display New UUID (RHEL/CentOS, SLES/OpenSUSE):

tune2fs /dev/sdb1 -U random
dumpe2fs -h /dev/sdb1 | grep UUID
