Complete the steps in the following procedures to debug iSCSI backend
sessions.
Note: iSCSI backend sessions are not supported on 100g ports.
- Run the command lseventlog to check the system event log. If the issue is
resolved by following the directed maintenance procedures (DMPs), then no further action is
required. If the issue is not resolved, complete the following steps to debug iSCSI sessions.
- Run the command lscontroller
controller_id | controller_name for the MDisk that is in degraded/offline
state. In the detailed view, note the values for the field iscsi_port_id.
- Issue the command svcinfo lsiscsistorageport, map the values from step 2, and
verify the status field.
- If the status is not full, then obtain a detailed view for that particular session by using the
command svcinfo lsiscsistorageport
sessions_row_id.
- In the detailed view of lsiscsistorageport from step 4, check the values of
the field connected. It indicates which nodes, which src_ip,
is having an issue. The src_port_id and node_id attributes are
also available in the detailed view.
- Using the command svcinfo
lsportethernet, check the link status for the src_port_id and node_id tuple.
- If link status is not active, check the physical connection of the
cable/small form-factor pluggable (SFP) transceiver.
- Check the port status of the particular port on the switch.
