HP P2000 G3 MSA - server 2008r2 disk management



I have a SAN HP MSA P2000 and multiple volumes mapped to different machines.
I have succesfully managed to map 1 iSCSI volume to a windows server 2008r2 machine a while ago. Now I wanted to add another volume, (from the same SAN target) to the same machine;
After I have mapped the volume to the host (from san cli), now in iSCSI initiator on the server I can't detect the 2nd volume; Nor in disk management;
The 1st iscsi volume is still detected in initiator and shows up in disk management;
The target is listed as discovered and connected in initiator on the server;

What should I do to force detect the new volume?
Rescan disks doesn't discover the volume;
I can't reboot the server cause it';s highly critical

I've disconnected the existing mapped disk, deleted the target in iscsi initiator, re-added target, rediscovered disks and still only the 1st one was detected. The 2nd one is nowhere...

Thanks in advance;

SAN config:
Host View [ID (iqn.1991-05.com.microsoft -NS NAME SERV Name (hostname) Profile (Standard) ] Mapping:
Name Serial Number LUN Access Ports
san_bckpvolume002 00c0ffxxxxxxxxxxxxxxxxxx01000000  220 read-write A1,A2,B1,B2    (discovered, mapped, in use)
san_bckpvolume401 00c0ffxxxxxxxxxxxxxxxxxxf01000000 401 read-write A1,A2,B1,B2   ( not discovered at all)

the problem was with the lun number; apparently win 2008r2 doesn't get along very well with lun numbers higher than 30x something...
