Rescanning new Fibre-Channel LUNS on ESX-Server 2.01

[Douglas Garstang]

All,

Have ESX 2.01 installed.

The vmware documentation says that after adding new SAN/Fibre Channel
storage, you need to manually rescan in the Linux os with either of
the following:

echo "scsi-qlascan" > /proc/scsi/qla2200/<numeric_entry>
or
vmkfstools -s <FC_SCSI_adapter>

Neither of these commands actually adds a new LUN to the
/proc/scsi/qla2200/0 file... However doing a rescan in the 'Storage
Management' section of the vmware GUI does. Why???

Also, LUNs are never removed from the /proc/scsi/qla2200/0 file until
a reboot. Performing both a manual rescan AND a gui rescan does not
remove entries. The result is that the GUI starts spitting out errors
presumably because the entries still exist in the /proc/scsi/qla2200/0
file... eventhough they are physcally no longer present.

So... why does the manual rescan have no effect and why aren't entries
ever removed from the /proc/scsi/qla2200/0 file? How do you remove
these entries without a reboot?

Help appreciated...
Doug.
