Do: iscsiadm -m session -r $SID --rescan you get the SID from iscsiadm -m session (it is the value in the []) or if you do iscsiadm -m session -P 3 you can see which session lines with with which lun. or iscsiadm -m node -T target --rescan or you can just take the lazy way and do iscsiadm -m session --rescan which rescans everything. The above commands will rescan existing devices and add new ones. It will not remove old ones. But if you have a disk mounted or have something like LVM or dm-multipath using a disk then you probably need to run one of those tools to pick up the change there. Oh yeah I do not remember if this is in 865. It might only be in the newer 865.X and new 869 releases on open-iscsi.org. > > P.S.

If not then check out the README with that release (older 865's may not have up to date READMEs though). > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
