The lsfabric command generates a report that displays the connectivity between nodes and other controllers and hosts.
Syntax
>>- svcinfo -- -- lsfabric -- ----------------------------------> >--+-------------------------------------------------------+--->< +- -node -- node_id_or_name -- --+--------------------+-+ | '- -port -- port_id -' | +- -wwpn -- wwpn ---------------------------------------+ +- -host -- host_id_or_name ----------------------------+ +- -controller -- controller_id_or_name ----------------+ '- -cluster -- cluster_id_or_name ----------------------'
Parameters
- -node node_id_or_name
- (Optional) Displays the output for all ports for the specified node. The only parameter that you can specify with the -node parameter is the -port parameter.
- -port port_id
- (Optional) Displays a concise view of all WWPNs that are logged into the specified port ID and node. The -port parameter must be specified with only the -node parameter. A valid port_id value is a number from 1 - 4 that specifies the port number in the vital product data (VPD) or the hexadecimal WWPN of the local port.
- -wwpn wwpn
- (Optional) Displays a list of all ports that have a login to the specified WWPN. You cannot use the -wwpn parameter with any other parameter.
- -host host_id_or_name
- (Optional) Specifies a host name or ID. Issuing the lsfabric command with the -host parameter is equivalent to issuing the svcinfo lsfabric -wwpn wwpn command for every configured WWPN of the specified host. For example, a host with two ports that are zoned to one port of every node in a eight-node cluster produces 16 lines of output. You cannot use the -host parameter with any other parameter.
- -controller controller_id_or_name
- (Optional) Specifies a controller ID or name. You cannot use the -controller parameter with any other parameter in this command. Issuing the lsfabric command with the -controller parameter is equivalent to issuing the svcinfo lsfabric -wwpn wwpn command for every configured WWPN of the specified controller. For example, a controller with 4 ports connected to a 8 node cluster with 2 counter part SANs produces 64 lines of output.
- -cluster cluster_id_or_name
- (Optional) Specifies a cluster ID or name. You cannot use the -cluster parameter with any other parameter. Issuing the lsfabric command with the -cluster parameter is equivalent to issuing the svcinfo lsfabric -wwpn wwpn command for every known WWPN in the specified cluster. Output is sorted by remote WWPNs and then cluster WWPNs. This parameter can be used to check the state of connections within the local cluster or between the local and remote cluster. When the local cluster ID or name is specified, each node-to-node connection is listed twice: once from each end. For example, an eight-node cluster with two counterpart SANs produces eight nodes, multiplied by seven other nodes, multiplied by two SANs, multiplied by four point-to-point logins, equals 448 lines of output.
Description
The lsfabric command can be issued with any of the parameters to display a limited subset of information. If the command is issued without any parameters, it provides output for every node.
Values for
the Type and State columns are:
- state active
- The meaning of this value depends
on the object
that it applies to, as follows:
- host or controller: SCSI commands were issued within the last 5 minutes.
- node: node ports can see other ports.
- state inactive
- No transactions have completed within the last 5 minutes.Note: It can take up to 10 seconds after a command for a controller port to change from inactive to active. It can take up to 5 minutes after a command for a host port to change from inactive to active.
- type
- One of the following values is
displayed:
- host
- node
- controller
- unknown
You can issue this command to view all the information about the connections that are available to your cluster.
