PowerScale: Viewing Statistics for a PowerScale Node
Summary: Basic commands to view some health information and statistics for a node.
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%)
Used: 227G ( 4%)
Network Status:
See 'isi networks list interfaces -v' for more detail or man(8) isi.
Internal: 2 IB network interfaces (1 up, 1 down)
External: 2 GbE network interfaces (1 up, 1 down)
2 10GbE network interfaces (2 up, 0 down)
2 Aggregated network interfaces (0 up, 2 down)
