This tutorial shows
how to use the command line in ESXi 5.5 to mount iSCSI LUNs from a
Linux server.
Using an Arch Linux
box that's already configured as an iSCSI server and has a few LUNs
mapped.
The process on the
ESXi is:
- start iscsi
- discover targets
- mount LUNS
Starting software
iscsi on ESXi:
~ # esxcfg-swiscsi
--enable
Enabling software
iSCSI...
~ #
To check the status
of the iSCSI adapter:
~ # esxcli iscsi
adapter list
Adapter Driver

There is a dinamic
way to perform iscsi discovery (All available targets) or static
(specify target name to be discovered).
I am using static discovery:
~ # esxcli iscsi
adapter discovery sendtarget add -a 172.16.41.132 -A vmhba33
I need to rescan the
adapter(s). In this example I rescan all adapters.
~ # esxcli storage
core adapter rescan –all
I can also rescan
the iscsi adapter only:
~ # esxcli storage
core adapter rescan --adapter vmhba33
My initiator has now
an iqn assigned to it.
~ # esxcli iscsi
adapter list

I should be able to
see now all the paths to the LUNs
~ # esxcfg-mpath -l
The output is a long
list of LUNs and their available paths. The status should be active.
I can also use
esxcli for this info.
~ # esxcli storage
core path list
The next steps are
to use partedUtil and vmkfstools to format and create the new
datastores, or vShpere Client.
