Dear list, Forgive me if my terminology is not entirely correct, since I'm not a mainframe configurator.
At the moment we do a power-on reset and IPL's of the hosts to activate new MCL's for the OSA-cards. According to IBM, applying and activating MCL's can be done without disruption. All our hosts have at least two OSA-ports, each port on an other OSA-card ( OSA Express2 ). I can deactivate the CHPID of an OSA-port on all LPAR's that use that port, and then put the PCHID in service mode. Network traffic will then continue, without disruption, over the remaining OSA-port. After applying the new MCL, I can activate the PCHID, CHPID's and ofcourse the TCP/IP-port. Then I can do the same procedure for the remaining OSA-port Halfway during this procedure, there is a moment when the two OSA-ports have different microcode levels. Did anyone ever experience problems, using different MCL's? Is there another way to activate the MCL's without disrupting the hosts? -- Maarten Slegtenhorst ----------------------------------------------------------------- ATTENTION: The information in this electronic mail message is private and confidential, and only intended for the addressee.
