I really don't know what I did, but I was trying to extend a iSCSI LUN. Using OpenFiler. I have a cluster, currently mixed w/ ESX 4.1 and ESX 5 hosts. My ESX 5 hosts I was able to get the iSCSI LUN to show up fine...but it's my ESX 4.1 hosts that I am having the issue on...
If I look at "Devices" under Storage, I see the LUN "t10.F405E46494C4542564C474F49613D283056485D297639524", however if i go to DataStores I got nothing for iSCSI LUN. I've tried rescanning the HBA's no luck.
What sort of concerns me here is the LUN ID...if you notice in the screen shot, LUN ID 0 represents some local storage as well as the iSCSI device.
Furthermore I list my disks from the console I.E. /vmfs/devices/disks is see the same iSCSI identifier but it's listed twice...the second has a :1 at the end...Normal?
t10.F405E46494C4542564C474F49613D283056485D297639524
t10.F405E46494C4542564C474F49613D283056485D297639524:1
How can I get that LUN back? And WITHOUT REBOOTING the hosts. I don't have a SAN...yea I know...painful, but am working toward getting one purchased cause this local storage is really a PITA...
If there is a way to forcibly remove the iSCSI device from all hosts, then I can go that route. There is NO data on this LUN so I can delete it if possible...and since when I go into Devices and if I right click on the iSCSI LUN, I don't get any unmount, detach or delete options...
Any ideas?
