The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.

Optionally, this utility can be used to list the current…
IBLINKINFO – report link info for all links in the fabric Synopsis iblinkinfo <options> Description iblinkinfo reports link info for each port in an IB fabric, node by node.

IBIDSVERIFY – Validate Ib Identifiers In Subnet And Report Errors Synopsis ibidsverify.pl [-h] [-R] Description ibidsverify.pl is a perl script which uses a full topology file that was created by ibnetdiscover, scans the network to validate the LIDs and GUIDs in the subnet. The validation consists of checking that there are no zero or duplicate…
IBHOSTS – show InfiniBand host nodes in topology Synopsis ibhosts [options] [<topology-file>] Description ibhosts is a script which either walks the IB subnet topology or uses an already saved topology file and extracts the CA nodes. Options -C, –Ca <ca_name> use the specified ca_name. -P, –Port <ca_port> use the specified ca_port. -t, –timeout <timeout_ms> override…
IBFINDNODESUSING – Find A List Of End Nodes Which Are Routed Through The Specified Switch And Port Synopsis ibfindnodesusing.pl [options] <switch_guid|switch_name> <port> Description ibfindnodesusing.pl uses ibroute and detects the current nodes which are routed through both directions of the link specified. The link is specified by one switch port end; the script finds the remote…
