dynamic disks configurations on win 2k servers

I have a group of Windows 2000 servers that are plugged into a SCSI fiber
channel fabric as part of a SAN (storage area network). One of the features

of this SAN is the ability to dynamically assign SCSI devices to any given
server on-the-fly. (for e.g. when I create snapshots and assigns to a
particulart server). I need to write a utilty, that will allow win2K servers

to to detect, scan, index, and assign the drive letter of my choice to a
device that has been added to the server.

Anyone out there done this and willing to share?

TIA

Your FC vendor should have mapping software. That, in conjunction with Disk
Manager should be able to handle that. You may need to use the vendor’s
utility
software to re-login to the fabric or to query the nameserver.

LDM/vxvm can do this when asked to rescan the disks. I want to do it inside
my application. I think I can use IOCL_SCSI_RESCAN_BUS and
IOCTL_STORAGE_FIND_NEW_DEVICE. I have another problem, how to list all
FC-HBA on the host?
Please comment if this is a correct approach?

thanks

dynamic disks configurations on win 2k serversUse PnP APIs to re-enumerate the SCSI bus, the same functionality as “Scan For Hardware Changes” in PnP manager.
