ssa_speed Command
Purpose
To determine the operating speed of SSA links.
Syntax
Description
The ssa_speed command either tests the existing link speeds of the selected pdisk or
adapter, or searches for link speed exceptions on all SSA adapters in the using system.
Flags
-l pdisk
-a AdapterName
-s
-p Loop
-n Network
-x
-e
Specifies the pdisk that you want to test.
Specifies the adapter that you want to test. If you select the -a flag, you must
also select the -p or the -n flag.
Specifies the supported link speed.
Causes the ssa_speed command to show the operating speed of both ports.
Valid Loop parameters are: A, a, B, b (for example, -p A, -p b).
Causes the ssa_speed command to show the operating speed of all ports on
the selected network. Valid Network parameters are: A, a, B, b (for example, -n
A, -n b).
Causes the ssa_speed command to test each adapter on the using system for
link speed exceptions on all nodes. To do this, the command inspects the
Supported Speed and the Current Speed for each pair of neighboring nodes in
each network. If the Current Speed of a particular pair of nodes is less than
the Supported Speed of the slowest device in that pair of nodes, the command
returns the message:
lowest <port_hop> count of the tested pair.
When used with the -x flag, the -e flag generates an error log entry if a link
speed exception condition is detected.
