After a successful ISSU (upgrade) or ISSD (downgrade) of an MDS 9718 switch: 1. Devices are not able to FLOGI into a switch. The devices can be new or one that was previously logged into successfully but were logged out due to a host reload or other event that takes link down. 2.

This issue only occurs on MDS 9718 switches when there are modules in the 2nd and 18th slots and the module in the 18th slot fails during the ISSU. When the module in the 18th slot reloads it would normally come up at the new code level. Upgrade flag is left as TRUE for a module 2 as a result of this. The entire FLOGI process is waiting for the FLOGI process in module 2 to complete before processing any FLOGIs. This status can be confirmed with the show flogi internal info | include Upgrade|Node: next 4 command: Upgrade in progress TRUE 1; dpvm en[0] vmis en[0] npiv en[1] evfp en[1] Node: 202 Ports: 48 Present TRUE Upgrade:TRUE mod_info: 0x1027bed4 port_size_obsolete: 32 num_vports: 0 num_ports_obsolete: 32 slot: 1, nodeid: 0x202, rid: 0x0, is_present: 1, upgrade: 1 "Upgrade in progress TRUE 1" indicates the FLOGI process is waiting for ISSU to complete. "Node: 202 Ports: 48 Present TRUE Upgrade:TRUE" and "slot: 1, nodeid: 0x202, rid: 0x0, is_present: 1, upgrade: 1" both indicate that module 2 considers ISSU to be still in progress
The following hidden command can be used to turn off the upgrade flag on module 2: switch123# debug flogi test do_lc_upg_over slot 2 proc 2 node_id 0x202 lc_node 0x202 Request sent Response received
None.
The module id is correctly handled and the upgrade flag is correctly turned off.
