iSCSI target rebooting causes initiators to reboot as well

view story

http://serverfault.com – I'm running a couple of iSCSI Targets with OCFS2. I had to reboot my iSCSI Target (the physical iSCSI Target) due to some hardware changes and it caused all the initiators to reboot. I want to prevent that or at least make them wait a lot longer before they reboot. Is there some sysctl variables I can use to modify the targets? I have multiple iSCSI Targets on my main system, due to need to share them out with multiple systems I'm running OCFS2 as the Filesystems on the Initiators (HowTos)
