SDCLI. Unable to create LUN (iSCSI RDM)

gmilazzoitag — Thu, 05 Jun 2025 06:06:00 GMT

Hi. Using Snapdrive from GUI and passing it the same parameters of the command line works. No change to have it using sdcli

My command is:

sdcli disk create -d D -p filer:/vol/volname/lunname.lun -z 491520MB -IG vmwaresrv01 rcu_generated -dtype dedicated -ds DSP_ROM10

I get the error (EX01 is the server from where I execute SDCLI):

EX01 : Checking input parameters

EX01 : Checking access control

EX01 : Checking policies

Unable to create LUNs.

Error: No igroup found for the current node.

DSP_ROM10 is the iSCSI datastore where to put the rdm file, rcu_generated is the igroup name containing all the iqn of the vmware esx forming the cluster and vmwaresrv01 is the vmware esx server hosting EX01 vm.

I've also tried to put between " the DSP_ROM10 datastore name

Any idea? Help?

can you please post the output for sdcli igroup list -m "hostname" -f "filer ipaddress"

Already tried. It's correct. In my opening post I've changed some name for privacy reasons...anyway the REAL command is

sdcli disk create -d D -p itromfs10:/vol/rom_exchange_ex01_users_data/rom_exchange_ex01_users_data.lun -z 491520MB -IG itromvm12 rcu_generated -dtype dedicated -ds DSP_ROM10

I've a doubt. Should I put the iqn and not the host name? Manuals seems to say "hostname" and not iqn

C:\Program Files\NetApp\SnapDrive>sdcli igroup list -f itromfs10

MANUAL BRINGS ON THE WRONG PATH putting vmwsomething in the sample as name

In the IG parameter the pair is formed by the host name where's the LUN is creating and the igroup that contains the ESX iqn
