Thanks for report, I believe this was reported and fixed upstream as well - https://github.com/hreinecke/sg3_utils/issues/3 ... https://github.com/hreinecke/sg3_utils/pull/4/commits/66af0c64749682e5d5dfcb372e2e521b5a583794 patch is supposed to correct this wrong behaviour. Can you please check this and confirm the fix if possible? The patch would be:

Description of problem: Version-Release number of selected component (if applicable): From sg3_utils-1.28-6.el6 In sg3_utils-1.28-5, `rescan-scsi-bus.sh --luns=1` will only rescan luns numbered 1, which is expected. Starting from sg3_utils-1.28-6, `rescan-scsi-bus.sh --luns=1` will scan all luns, which we don't like. How reproducible: Steps to Reproduce: 1. Attach multiple SCSI disk to a RHEL6 VM. 2. Run `rescan-scsi-bus.sh --luns=1` Actual results: It scan all luns. ~]# ./rescan-scsi-bus-test2.sh --luns=1 which: no multipath in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin) Scanning SCSI subsystem for new devices Scanning host 0 for SCSI target IDs 0 1 2 3 4 5 6 7, LUNs 1 Scanning for device 0 0 0 0 ...
