How to simply unlink an iscsi volume from esx

[Ritmo2k]

How do I do this non destructively?

The way I am doing it causes esx to warn me the volume will be removed and all the contents deleted.

Thanks!

Do you have a dynamic entry for the iscsi volume? If so remove it and then rescan the iscsi adapter, the lun should go away.

You could also put in a bad password and rescan but you want to remove the entry if it exists.

You are correct, remove = delete partition, don't do that if you want to keep the data!

To unmount a partition unmap the iSCSi volume from you ESX host on the iSCSI side and then do a rescan of the iSCSI adapter on the ESX side, the LUN will be automatically unmounted when the server can no longer see the LUN.

Is correct to say: Because of the design of VMFS (cluster aware) no data can be cached within the operating system (in opposite to NTFS), so unmounting a volume at the ISCSI TARGET side is safe. Shut down all machines using ISCSI, stopping all script etcand waiting a minute is safe !
