If all directors are set to Principal or Default, the switch with the highest priority and the lowest WWN becomes the principal switch. Following are some examples of principal switch selection when directors have these settings: - If you have three directors and set all to Default, the director with the lowest WWN becomes the principal switch. - If you have three directors and set two to Principal and one to Default, the director with the Principal setting that has the lowest WWN becomes the principal switch. - If you have three directors and set two to Default and one to Never Principal, the switch with the Default setting and the lowest WWN becomes the principal switch. Note that at least one director in a multiswitch fabric needs to be set as Principal or Default. If all of the directors are set to Never Principal, all of the interswitch links (ISLs) will segment. If all but one switch is set to Never Principal and the director that was principal goes offline, then all of the other ISLs will segment. Note We recommend you leave the switch priority setting as Default. If you are considering setting this value to something other than default, refer to the section on principal switch selection for multiswitch fabrics in the hp surestore director fc-64 Planning Guide (HP A6534-90903) for details. In the audit log, you may notice that the Principal setting maps to a number code of 1, Default maps to a number code of 254, and Never Principal maps to a number code of 255. The number codes of 2 - 253 are not currently in use. • Rerouting Delay Placing a check mark in the check box to the left of the Rerouting Delay option enables rerouting delay. This option is only applicable if the configured director is in a multiswitch fabric. The default state is disabled. Enabling the rerouting delay ensures that frames are delivered in order through the fabric to their destination. If there is a change to the fabric topology that creates a new path (for example, a new switch is added to the fabric), frames may be routed over this new path if its hop count is less than a previous path with a minimum hop count. This may result in frames being delivered to a destination out of order since frames sent 112 Configure Operating Parameters

Configure Operating Parameters

If all directors are set to Principal or Default, the switch with the highest priority and

the lowest WWN becomes the principal switch. Following are some examples of

principal switch selection when directors have these settings:

–

If you have three directors and set all to Default, the director with the lowest WWN

becomes the principal switch.

–

If you have three directors and set two to Principal and one to Default, the director

with the Principal setting that has the lowest WWN becomes the principal switch.

–

If you have three directors and set two to Default and one to Never Principal, the

switch with the Default setting and the lowest WWN becomes the principal switch.

Note that at least one director in a multiswitch fabric needs to be set as Principal or

Default. If all of the directors are set to Never Principal, all of the interswitch links

(ISLs) will segment. If all but one switch is set to Never Principal and the director that

was principal goes offline, then all of the other ISLs will segment.

Note

We recommend you leave the switch priority setting as Default. If you are

considering setting this value to something other than default, refer to the

section on principal switch selection for multiswitch fabrics in the

hp surestore

director fc-64 Planning Guide

(HP A6534-90903) for details.

In the audit log, you may notice that the Principal setting maps to a number code of 1,

Default maps to a number code of 254, and Never Principal maps to a number code of

255. The number codes of 2 - 253 are not currently in use.
