I need assistance to setup DM-Multipath with Hitachi arrays and need online addition of LUNs afterwards as we get n amount requests for storage expansion. Please let me know whether there are any known issues/problems with the above given and what should i use to get the LUNs detected without a reboot to the server(s). We have a excess of 300 servers. Please help.
Regards
Solved! Go to Solution.

SolutionAvoiding a reboot is nearly impossible.
You can install PSP for proliant systems. That includes a new kernel and to get full benefit you need to do a reboot.
Perhaps if the disks are all set up and zoned to the HBA's by WWN, you can use the hp_rescan utility to detect the disks without a reboot.

Re: SAN-Redhat
we use the combinations of those commands, but not limited to.
echo "scsi-qlascan" > ${HBA_DIR}/${HBA_NUM}
echo "scsi add-single-device ${HBA_NUM} ${CHN} ${ID} ${LUN}" > /proc/scsi/scsi

the fibreutils package contains hp_rescan which will find you HBA's and force a rescan
