7.2. Configuring CLI tool¶
Before you can use the vstorage-target
CLI tool to export volumes via iSCSI, set it up, as described below. Perform these steps on each node where you plan to run iSCSI targets.
Create a configuration file
/etc/vstorage/iscsi/config.json
with at least these mandatory parameters:{ "ClusterName": "cluster1", "VolumesRoot": "/vols/iscsi/vols", }
Where
ClusterName
is the name of your storage cluster andVolumesRoot
is the path to the directory for iSCSI volumes.You can also set these optional parameters:
"PcsLogLevel"
: the log level, ranges from 1 (log errors only) to 7 (log all, including debug messages)."LogPath"
: the path to log files, the default is"/var/log/vstorage"
(the log will be saved tovstorage-target.log
)."GetTimeout"
: the timeout for the initiator’s command to read target port group status, the default is 3000 ms.
Enable the target monitor service:
# systemctl start vstorage-target-monitor.service # systemctl enable vstorage-target-monitor.service
Create the iSCSI volume directory if it does not exist:
# mkdir -p /mnt/vstorage/vols/iscsi/
If you modify the configuration file later, restart the TCM monitor service to apply changes:
# systemctl restart vstorage-target-monitor.service
