Can somebody please provide links/info on the progress being made on device detection for RHEL/SuSE? I constantly have issues when my storage admin presents me new LUNs and I cannot get the running o/s to pick them up. RHEL's kudzu is not ready for prime time and the open source stuff I've tried (unsuccessful with several SCSI-scan scripts, right now testing QLogic's Dynamic TGT Lun Discovery tool) also hasn't worked so far. If anyone has a tool that consistently works, please share it. I'm running RHEL4/5 as well as SuSE 9 on HP blades.

Any help, or pointers, or discussion would be appreciated.
Thanks

I use RHEL4.x servers and qlogic24xx HBA's as a standard.
I used to have a HP EVA 5000 storage frame and now have IBM storage frames virtualized via an SVC (San Volume Controller).
I never have issues presenting new storage in realtime with commands:
#> echo "1" > /sys/class/fc_host/host0/issue_lip
#> echo "- - -" > /sys/class/scsi_host/host0/scan
#> echo "1" > /sys/class/fc_host/host1/issue_lip
#> echo "- - -" > /sys/class/scsi_host/host1/scan

(Note: on some servers, my HBA cards show up as /sys/class/fc_host/host2 and /sys/class/fc_host/host3 - so the above lines would have to be adjusted for that.)

I do agree the Windows servers appear to have better handling of dynamic storage (e.g. removal of LUN's in realtime), but as I can't make my own drivers, I am happy to use what others have done thus far.
P.S. I turn on Kudzu when I build a server.

thanks zQUEz...
