Full Discussion: Scan For new LUNS

As long as the driver for the HBA has been loaded, then you should not need to update anything further unless you are using multipath drivers.

For that, you should update the multipath configuration files according to how your vendor specifies they should be modified.

If you need to rescan for LUNs on an active machine, there are a few ways. One of which is to find the script (available for free online) rescan-scsi-bus.sh

Alternately you can echo '- - -' to /sys/class/scsi_host/host<num>/scan

Code:
echo '- - -' > /sys/class/scsi_host/host1/scan

but you should do this for all HBAs.

DESCRIPTION

       The  iscsi driver is a software initiator that transports SCSI commands over TCP/IP as described in RFC 3720. The initiator is administered
       through iscsiadm(1M). The iscsi initiator acts as a host adapter driver that attaches the appropriate target driver (for example sd(7D) for
       disks or st(7D) for tapes) for devices it discovers. See the System Administration Guide for more information.

FILES

       /kernel/drv/iscsi	    32-bit ELF kernel driver.
