Fast Fabric InfiniBand Externally Managed Switch Setup/Admin Menu
2-16 IB0054607-01 A
If any switches fail to be updated, use the View iba_switch_admin result files
option to review the result files from the update. Refer to FastFabric Command
Line Interface Reference Guide for more details.
Setup Switch Basic Configuration
(Switch) This will run the iba_switch_admin configure command which will
prompt for switch configuration settings and then configure all the selected QLogic
12200 switches accordingly. The following aspects of switch configuration may be
set:
 Maximum MTU size
 VL Capability
 Link Layer Credit Distribution
 Link Width Supported
 Link Speed Supported
 IB Node Description
NOTE:
Since the InfiniBand fabric itself is used to update externally managed
switches, updating multiple switches with the reboot option may disrupt
parallel update operations. If there are no selected externally managed
switches in the path from the InfiniBand Management Node to any other
externally managed switch, parallel operations may be used. For example if
an InfiniBand Management node is connected directly to a core switch and
the externally managed switches are only at the edges. If in doubt, do not
use parallel update. Be aware that non-parallel operation for a fabric with
many externally managed switches could take a significant amount of time.
Another alternative is to perform the update in parallel without a reboot and
then perform the reboot separately using the Reboot Switch menu
selection. To control the order of the rebooting of externally managed
switches by FastFabric, see the discussion of the distance value in
“Externally Managed Switch List File” on page A-13.
NOTE:
Normally, the IB Node Description is updated as part of a firmware upgrade;
however, the user is given the option to update the node description outside
of an upgrade procedure.
