Hello Dick ,
is there something new about the sys$fwdriver and "control timeout" problem ?
it happens a customer of mine has got the same problem than the preceding
replies ; i did enter it as note 1990 as the symptom perceived by the customer
was lost of the cluster connection and from lancp , address going to
00-00-00-00-00-00 , and as i've gone a lot further ,
it is more detailed below :
================================================================================
Note 1990.0 DEFPA and OpenVMS losing MAC address No replies
TOOPCS::SELLES 21 lines 20-MAR-1996 11:59
--------------------------------------------------------------------------------
in the following customer configuration , we have a strange problem of
the DEFPA losing its mac address ( all going to 00-00-00-00-00-00 ) during
normal system operation: this is detected by looking at MC LANCP sho conf
configuration is :
alpha axp openvms 6.2 with latest axp_lan patches and PCI DEFPA SAS RJ45
latest
firmware ( 2.46 )
connected to
fddi decconcentrator 900 MX with latest firmware 3.2.2 ; RJ45 connectors ;
this is a axp cluster with server 2100 with EISA card ( no problem ) and
3 stations PCI card : the problem can occur on any of the 3 stations so we
dont suspect hardware fault on the card
as anyone encountered the same problem ?
thanks for any light or idea
PJ
--------------------------------------------------------------------------------
More details :
i did some investigation in the customer configuration and uncovered the
same problem as described in this note with errorlog messages as
"fatal error detected on datalink" and also , as it is a cluster ,
"pea0 : port has closed virtual circuit" , as cluster switches from FDDI to
Ethernet ;
this problem can occur randomly on any of the 3 alphastations with DEFPA card
, and never happens on the alphaserver with DEFEA card ;
plus the fddi driver sys$fwdriver can failed either at boot time , or during
normal system operation ( the problem can happen 1 time per day )
the only workaround is to reboot the station ( power off / power on );
i dont suspect the DEFPA cards as i discovered the following behaviour :
- i power on the station : the DEFPA inits and set up the link with the
concentrator900mx ( port is up from 900mx , green led on from DEFPA ) ;
- i boot openvms : if there is a "control timeout" , the card deactivates
the link ( port down , led off ) and SDA gives the results below ;
if there is no problem , the link stays up ;
- if openvms up and running , and there is a "control timeout" problem ,
card deactivates link , errorlog messages and SDA results as below and lancp
shows address all 0's
- i shutdown OpenVMS ( the link being down ) and keep the station power on
, and then , the card re-inits itself and the link goes up again !!!
so this is why i suspect rather a problem with the sys$fwdriver
below , is results of SDA after problem at boot time , but the symptoms are
the same if it happened during normal operation ( besides the FDDI counters
being incremented )
i have highlighted what is different from a "normal result" with >>>>>>> lines
