Issue

QPM installed in a director, a cable move followed

by a port speed change under specific conditions

may cause an erroneous entry in the nameserver

for a disabled port. The sequence of events that

could cause this are: 1) a QPM is configured with

all port speeds set to burst mode 2) there are active

links on an odd number port (1 or 3) and on the

even number port that is not its corresponding sus-

tain mode port (2 or 0, respectively). 3) the link to

the odd numbered port (1 or 3) is moved to its cor-

responding sustain mode port (0 or 2, respectively)

4) the port speed for the other even numbered port

is changed to sustained mode 5) the entry for the

odd number port that was moved (disconnected)

may re-appear in the nameserver

In a FICON environment, if a connected device has

zero Buffer-Buffer (BB) credits, a PLOGI to that device

from other devices may fail unless the BB credits

recover.

If a switch has been managed with HAFM/EFCM

Management Style configured to FICON Manage-

ment Style, and the Prohibit Dynamic Connectivity

Matrix (PDCM) has been configured with Act-

ive=Saved disabled, and the HAFM/EFCM

Management Style is changed to Open Systems

Management Style, and the switch is power

cycled, when the switch power on reset is executed,

the PDCM configuration is set to the previously act-

ive configuration instead of the configuration of the

contained in the IPL file.

When replacing a port card module a configured

Preferred Path with a source port that is part of the

newly installed port card module is cleared, while

a configured Preferred Path with an exit port that is

part of the newly installed port card module is not

cleared.

Workaround

If this is issue is encountered, configure both the even

ports of the QPM card to sustained mode instead of

configuring only one.

Blocking and unblocking the switch port of the device

will allow the PLOGI to succeed.

If the switch has been configured as described, review

and modify the PDCM as needed after a power cycle.

If the Preferred Path entry is cleared when a port card

module is replaced, the Preferred Path must be re-

entered.
