(unresolved) : strange hme0 messages in the log file
2007-12-25 11:36:00
my original question is at the end of this email
well, the problem is not entirely solved yet, i guess its a wait and
watch game that i'm going to have to play here.
a lot of ppl replied saying that the message was normal and everything
was fine. but that fact is that its only these new ultra30 and ultra5
machines which are giving this message in /var/adm/messages. none of my
older ultra1's or ultra2's or hp's or sgi's have ever shown this, other
than at boot time.
ppl suggested that i check my ethernet connections and hub... i did ,
the cables are fine and the switch is configured properly, and doesnt
show any resets or errors. Its a superstack by 3com.
it was also suggested to confirm the interface was not running in debug
mode by looking that flags in the ifconfig output.
one person said that it is a known problem with solaris2.5.1 with
auto-negotiating with some switches. the way to fix this is lock the
workstation to 100BaseT full duplex mode with the following commands
ndd -set /dev/hme adv_autoneg_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_100fdx_cap 1
i did this and things were fine for a couple of days, until the "link
down-cable problem?" message showed up in the logs.
one more person shared a similar experience with me, in which an ultra5
showed the same behaviour. only , in his case, it had a RAID array
connected to it, while i have a backup device on the PCI-SCSI symbios
interface card. their only solution was to replace the ultra5. so, there
was no solution there either.
it seems to me increasingly, that these new ultra 5 line of workstation
from sun, arent good enough for heavy io.
thanks to all who replied. i appreciate your taking the time to help me
out here. i'll post a revised summary if we ever come to any conclusion
about this.

amol
