| + | ===== FC port masking ===== | ||
| + | |||
| + | You can limit FC traffic to specific purpose: | ||
| + | * for cluster traffic (inter-node) | ||
| + | * for remote copy traffic (replication) | ||
| + | |||
| + | <code> | ||
| + | -localfcportmask port_mask | ||
| + | (Optional) Indicates the Fibre Channel (FC) input/output (I/O) port mask for local system node-to-node communications only. | ||
| + | | ||
| + | -partnerfcportmask port_mask | ||
| + | (Optional) Indicates the FC I/O port mask for partnered system-to-system communications only. Fibre Channel port mask does not affect host or storage system traffic. | ||
| + | </code> | ||
| + | |||
| + | To view the current port mask settings, run the **lssystem** command, the output shows that all system ports allow all types of traffic. | ||
| + | <cli prompt='>'> | ||
| + | IBM_IBM FlashSystem:ITSO-FS9500:superuser>lssystem |grep mask | ||
| + | local_fc_port_mask 1111111111111111111111111111111111111111111111111111111111111111 | ||
| + | partner_fc_port_mask 1111111111111111111111111111111111111111111111111111111111111111 | ||
| + | </cli> | ||
| + | |||
| + | To set the local or RPORT mask, run the chsystem command. Example shows the mask | ||
| + | setting for a system with four FC ports on each node and that has RC relationships. Masks | ||
| + | are applied to allow local node-to-node traffic on ports 1 and 2, and replication traffic on ports | ||
| + | 3 and 4. | ||
| + | |||
| + | Example Setting a local port mask by running the chsystem command | ||
| + | <cli prompt='>'> | ||
| + | IBM_IBM FlashSystem:ITSO-FS9500:superuser>chsystem -localfcportmask 0011 | ||
| + | IBM_IBM FlashSystem:ITSO-FS9500:superuser>chsystem -partnerfcportmask 1100 | ||
| + | IBM_IBM FlashSystem:ITSO-FS9500:superuser>lssystem |grep mask | ||
| + | local_fc_port_mask 0000000000000000000000000000000000000000000000000000000000000011 | ||
| + | partner_fc_port_mask 0000000000000000000000000000000000000000000000000000000000001100 | ||
| + | </cli> | ||
| + | |||
| + | The mask is extended with zeros, and all ports that are not set in a mask have the selected | ||
| + | type of traffic blocked. | ||
| + | |||
| + | Specify the **lsportfc** command to display FC I/O port IDs. | ||
