Thanks. We'll let you know when a new response is added.

If your HBA is QLogic based, hit the downloads section of their website and get the “Linux Utilities” bundle and use “ql-dynamic-tgt-lun-disc” to do the scan. I do it all the time with EMC storage but the array shouldn’t matter for this.

but my HBA card is Emulex(HP BLc Emulex LPe1105-HP) so plz suggest to which tool required.

here not showing in /sys/class/fc_host/host 0 in /etc folder.plz suggest me.
