This support lets the user manage the target entries in adapter flash
and
perform various operations like add, delete, login, logout,
and update the target information.
The sysfs entries will look as cited below:
/sys/bus/iscsi_flashnode/devices/flashnode_sess-<host_no>:<flashnode_id>/<session
attrs>
/sys/bus/iscsi_flashnode/devices/flashnode_conn-<host_no>:<flashnode_id>:<conn_id>/<conn
attrs>
Operations using iscsiadm:
=========================
List all target nodes stored in the FLASH of the adapter
\# iscsiadm -m host -H hostno -C flashnode -o show
View all parameters of one particular flash node
\# iscsiadm -m host -H hostno -C flashnode -x <flashnode_idx> -o show
Update an entry and commit to adapter FLASH
\# iscsiadm -m host -H hostno -C flashnode -x <flashnode_idx> -n <name>
-v <value> -o update
Multiple name, value pairs can be specified in a single command for
update operation
Delete an entry
\# iscsiadm -m host -H hostno -C flashnode -x <flashnode_idx> -o delete
Create a new entry
\# iscsiadm -m host -H hostno -C flashnode -o new -A <ipv4/ipv6>
\# iscsiadm -m host -H hostno -C flashnode -x <flashnode_idx> -n <name>
-v <value> -o update
Example, create new entry:
\#iscsiadm -m host -H 7 -C flashnode -o new -A ipv4
Flashnode index: 2
New flashnode for host7 added
\#iscsiadm -m host -H 7 -C flashnode -o show
qla4xxx: [0] 192.168.1.12:3260,2
iqn.2002-03.com.compellent:5000d310004b0716
qla4xxx: [1] 192.168.1.12:3260,2
qla4xxx: [2]
Here - The newly created entry is at flashnode_idx 2, use it to update
the entry
\# iscsiadm -m host -H 7 -C flashnode -x 2 -o update
flashnode.conn[0].ipaddress -v 192.168.1.13
\#iscsiadm -m host -H 7 -C flashnode -o show
qla4xxx: [0] 192.168.1.12:3260,2
iqn.2002-03.com.compellent:5000d310004b0716
qla4xxx: [1] 192.168.1.12:3260,2
qla4xxx: [2] 192.168.1.13:3260,0
Login
\# iscsiadm -m host -H hostno -C flashnode -x <flashnode_idx> -o login
Logout
\# iscsiadm -m host -H hostno -C flashnode -x <flashnode_idx> -o logout
\# iscsiadm -m session -r sid -u
