Hi all:
I had one IB cluster with eight IBM HS21 blades, mixed with RHEL5.2 Server
and SLES10 SP2. All of them connected to one IB switch. opensm was running
as subnet manager on one blade. Command ibcheckerrors finished smoothly.
Last week I got another eight IBM LS21 blades connected to another IB
switch. But after I connected two switches and turned on all the IB
adapters on new blades, ibcheckerrors gave error message:
[EMAIL PROTECTED] ~]# ibcheckerrors

I had closed the embeded subnet manager on two IB switches. The issue
always exist, even after I change subnet manager location to another
machine. ib0 of machine gaia-07 can communicate with other machines each
other. All installed IB adapters are ConnectX 4xSDR. Both switches are
Topspin Switches. Will anyone give some advice about this issue? Thanks in
advance!
