Updating the Core Switch PID Format devices on the first fabric to be updated. (This is the best practice in cases where any doubt exists about the multi-pathing software's behavior, but is more labor intensive.) 3. Verify that I/O continues over the other fabric. 4. Disable all switches one at a time in the fabric to be updated. 5. Verify that I/O continues over the other fabric after each switch disable. 6. Change the PID format on each switch in the fabric, as follows: a. Telnet into each switch in the fabric. b. Type switchDisable, and press Enter. c. Type configure and press Enter. d. Type y at the Fabric parameters prompt, (yes, y, no, n): [no] y. e. To view the Core Switch PID setting, press Enter until you reach the Core Switch PID format line, similar to the following. Core Switch PID Format: (0..1) [0] Note: The [0] value shown above indicates the Core Switch PID parameter set on this particular switch. f. Type 1 to update the Core Switch PID format. g. Continue to press Enter until you have completed the configure section and have returned to the admin prompt. 7. One at a time, re-enable the switches in the updated fabric. In a core/edge network, enable the core switches first. 8. Once the fabric has re-converged, type cfgEnable myZoningCfg (where myZoningCfg is the name of your zone configuration). Press Enter to update zoning. Note: This does not change the definition of zones in the fabric, but causes the lowest tables in the zoning database to update with the new Core Switch PID format. 9. Repeat steps 3 through 6 for all fabrics in the SAN. 94 SAN Switch 2/32 Installation Guide

devices on the first fabric to be updated. (This is the best practice in cases
where any doubt exists about the multi-pathing software’s behavior, but is
more labor intensive.)
3.
Verify that I/O continues over the other fabric.
4.
Disable all switches one at a time in the fabric to be updated.
5.
Verify that I/O continues over the other fabric after each switch disable.
6.
Change the PID format on each switch in the fabric, as follows:
a.
Telnet into each switch in the fabric.
b.
Type
switchDisable
, and press
Enter
.
c.
Type
configure
and press
Enter
.
d.
Type
y
at the Fabric parameters prompt, (yes, y, no, n): [no] y.
e.
To view the Core Switch PID setting, press
Enter
until you reach the
Core Switch PID format line, similar to the following.
Core Switch PID Format: (0..1) [0]
Note:
The [0] value shown above indicates the Core Switch PID parameter set on this
particular switch.
f.
Type
1
to update the Core Switch PID format.
g.
Continue to press
Enter
until you have completed the configure section
and have returned to the admin prompt.
7.
One at a time, re-enable the switches in the updated fabric. In a core/edge
network, enable the core switches first.
8.
Once the fabric has re-converged, type
cfgEnable myZoningCfg
(where
myZoningCfg
is the name of your zone configuration). Press
Enter
to
update zoning.
Note:
This does not change the definition of zones in the fabric, but causes the lowest
tables in the zoning database to update with the new Core Switch PID format.
9.
Repeat steps 3 through 6 for all fabrics in the SAN.
