after the successful fail over from primary to backup RDEVs for the OSAs, what state was reported for the primary RDEVs? David
-----Original Message----- From: The IBM z/VM Operating System on behalf of Brian Nielsen Sent: Mon 4/24/2006 1:39 PM To: [email protected] Subject: [IBMVM] VSWITCH Controller failover issue on z/VM 5.2 This weekend the LAN team upgraded the CISCO router connected to the OSA = card. The VSWITCH controller console shows the message: DTCOSD309W Received adapter-initiated Stop Lan after which it tries to fail over from the primary OSA to the backup OSA.= Eventually I see: DTCOSD306I Received adapter-initiated Start Lan and the backup OSA addresses get started fine and assign all the IP addresses. There are several more iterations of Stop Lan and Start Lan, but it is = always on the backup OSA addresses, never on the primary OSA addresses. So the question is: why didn't it ever try to restart on the primary OSA = when the backup OSA received the Stop Lan? If both OSA cards were the = same it might not matter that much, but the primary is a Gig-OSA and the = backup is a Fast-OSA. ----- Oh, and just to make it more fun, lastly there is a Stop Lan, the various= normal messages about stopping, attempting to restart, and: AMPX036I ASSERTION FAILURE CHECKING ERROR TRACE BACK OF CALLED ROUTINES ROUTINE STMT AT ADDRESS IN MODULE SPSM_BLKALLOCATE 39 00D429D0 TCFPSM_FPSM INITDCB 48 00DA079A TCTOOSD_TOOSD TOOSDINIT 33 00DA2DF4 TCTOOSD_TOOSD CALLINITRTN 30 00CB9506 TCPARSE_PARSETCP PROCESSSTARTSTOPSTATEMENT 33 00CAE37E TCPARSE_PARSETCP PARSEOPTION 292 00CB3C00 TCPARSE_PARSETCP RECEIVECONTROLLERMSGFROMCP 25 00D9F010 TCTOOSD_TOOSD TOIUCV 180 00D3D580 TCTOIUC_TOIUCV Schedule 1670 00CFA118 <MAIN-PROGRAM> 14 00C441FE TCPIP VSPASCAL 00E4D74A DTCOSD100E Insufficient Fixed Page Storage Pool storage after which it tries to shutdown and then goes into repeated: AMPX015I ADDRESSING EXCEPTION abends. Needless to say there were a lot of dump files in spool space. So, IBM will get a call on the abends. I could add more virtual storage = to the controllers, but that will presumably only add cushion for more = stops & restarts before it runs out of storage again. Brian Nielsen
