In the following image, the LUNs panel displays the LUNs for a storage cluster.
Monitoring the status of file serving nodes
The dashboard on the GUI displays information about the operational status of file serving nodes,
including CPU, I/O, and network performance information.
To view this information from the CLI, use the
ibrix_server -l
command, as shown in the
following sample output:
ibrix_server -l
SERVER_NAME STATE CPU(%) NET_IO(MB/s) DISK_IO(MB/s) BACKUP HA
----------- ------------ ------ ------------ ------------- ------ --
node1 Up, HBAsDown 0 0.00 0.00 off
node2 Up, HBAsDown 0 0.00 0.00 off
File serving nodes can be in one of three operational states: Normal, Alert, or Error. These states
are further broken down into categories describing the failover status of the node and the status
of monitored NICs and HBAs.
Description
State
Up:
Operational.
Normal
Up-Alert:
Server has encountered a condition that has been logged. An event will appear in the Status
tab of the GUI, and an email notification may be sent.
Alert
Up-InFailover:
Server is powered on and visible to the Fusion Manager, and the Fusion Manager is
failing over the server’s segments to a standby server.
Up-FailedOver:
Server is powered on and visible to the Fusion Manager, and failover is complete.
Down-InFailover:
Server is powered down or inaccessible to the Fusion Manager, and the Fusion
Manager is failing over the server's segments to a standby server.
Error
Down-FailedOver:
Server is powered down or inaccessible to the Fusion Manager, and failover is
complete.
Down:
Server is powered down or inaccessible to the Fusion Manager, and no standby server is providing
access to the server’s segments.
The STATE field also reports the status of monitored NICs and HBAs. If you have multiple HBAs
and NICs and some of them are down, the state is reported as HBAsDown or NicsDown.
