Go to the volume settings, then the advanced tab and verify that the "allow simultaneous access from systems with different IQN names" is checked (the exact wording is slightly different, but it basically says that).
Without that checkbox checked, only 1 server at a time can access the volume (this is a safety feature probably to prevent people with Windows servers from blindly allowing multiple (non-clustered) Windows servers to access the same volume simultaneously).
i keep getting a problem where on this one esx server I have to remove the IQN SCSI name and readd it back into the access list before the server can see the luns. any idea why? prior to this I had rescanned the iscsi hba as well as rebooted. nothing seems to work. I had removed the dynamic discovery address in vsphere and readded. while it did add in under dynamic dicovery. the static discovery failed to discover the equalogic volume.
the fix was to remove it from the access list in the equalogic console and readd it back
