[Beowulf] Mellanox/Flextronics IB switch problem ?

[Gilad Shainer]

Hi Mikhail,

I general, I had no issues using Flextronics 8 port switches. I will try
to get someone to contact you for solving this issue.

I have following output from ibcheckerrors utility:

c5ws7:/home/guest # ibcheckerrors
#warn: counter LinkDowned = 20  (threshold 10) Error check on lid 1
(MT47396 Infiniscale-III Mellanox Technologies) port all:  FAILED
#warn: counter LinkDowned = 13  (threshold 10) Error check on lid 1
(MT47396 Infiniscale-III Mellanox Technologies) port 8:  FAILED #
Checked Switch: nodeguid 0x000b8cffff004037 with failure

LID 1 corresponds to our 24-port Flextronics F-X43044 switch. Does this
output means that there may be potential problems w/ port 8 or whole
switch  ?
