Upgrading Your Cisco MDS NX-OS Software Image

If this problem occurs, syslogs indicate a failure and the flapped ISL could remain in a down state

because of a domain overlap.

This issue was resolved in Cisco SAN-OS Release 2.1(2b); you must upgrade to Release 2.1(2b) before

upgrading to Release 3.3(1c). An upgrade from Cisco SAN-OS Releases 2.1(1a), 2.1(1b), or 2.1(2a) to

Release 2.1(2b) when IVR is enabled requires that you follow the procedure below. If you have VSANs

in interop mode 2 or 3, you must issue an IVR refresh for those VSANs.

To upgrade from Cisco SAN-OS Releases 2.1(1a), 2.1(1b), or 2.1(2a) to Release 2.1(2b) for all other

VSANs with IVR enabled, follow these steps:

Step 1

Configure static domains for all switches in all VSANs where IVR is enabled. Configure the static

domain the same as the running domain so that there is no change in domain IDs. Make sure that all

domains are unique across all of the IVR VSANs. We recommend this step as a best practice for

IVR-non-NAT mode. Issue the fcdomain domain id static vsan vsan id command to configure the static

domains.

Note

Issue the no ivr virtual-fcdomain-add vsan-ranges vsan-range command to disable RDI mode on all

Step 2

IVR enabled switches. The range of values for a VSAN ID is 1 to 4093. This can cause traffic disruption.

Note

Check the syslogs for any ISL that was isolated.

Step 3

2005 Aug 31 21:52:04 switch %FCDOMAIN-2-EPORT_ISOLATED:

%$VSAN 2005%$ Isolation of interface

PortChannel 52 (reason: unknown failure)

2005 Aug 31 21:52:04 switch %FCDOMAIN-2-EPORT_ISOLATED: %$VSAN 2005%$

Isolation of interface PortChannel 51

(reason: domain ID assignment failure)

Step 4

Issue the following commands for the isolated switches in Step 3:

switch(config)# vsan database

switch(config-vsan-db)# vsan vsan-id suspend

switch(config-vsan-db)# no vsan vsan-id suspend

Step 5

Issue the ivr refresh command to perform an IVR refresh on all the IVR enabled switches.

Step 6

Issue the copy running-config startup-config command to save the RDI mode in the startup

configuration on all of the switches.

Step 7

Follow the normal upgrade guidelines for Release 2.1(2b). If you are adding new switches running Cisco

MDS SAN-OS Release 2.1(2b) or later, upgrade all of your existing switches to Cisco SAN-OS Release

2.1(2b) as described in this workaround. Then follow the normal upgrade guidelines for Release 3.3(1c).
