Instructions

Here are a few basic commands to investigate the status of a node:

Overall status including network, storage capacity, drive, and throughput information

# isi status -n 1
Node LNN:             1
Node ID:              1
Node Name:            example-1
Node IP Address:      1.1.1.x
Node Health:          -A--
Node SN:              SS200-x-x
Member of Disk Pools: n/a
Member of Node Group: n/a
Member of Tier:       n/a
Node Capacity:       5.9T
Available:           5.7T (96%)

Network Status:
        See 'isi networks list interfaces -v' for more detail or man(8) isi.
Internal:            2 IB network interfaces (1 up, 1 down)
