I'm using LRBD to configure iSCSI targets from a Ceph cluster, LRBD uses Open-iSCSI/targetcli to configure the targets.
When I use an uppercase letter in the unique part of the iqn (after the colon), I get the following error message:
Invalid iqn wwn: iqn.1996-10.com.suse:enVolume1
If I change the V to be lowercase, the target is successfully created.
I can't find any information which says the iqn cannot contain uppercase letters after the colon, does anyone know what's causing this?
