[Lustre-discuss] lctl command usage

Greetings,

I am still working on tracking my lustre timeout/reconnect issue.
The lustre version on the OSS and MGS is
2.6.18-53.1.13.el5_lustre.1.6.4.3smp.   I am seeing IMP_INVALID
messages in my log files.   I think (not certain) that I have a bad IB
cable or port in a card, but I am trying to ascertain that it is not
perhaps another issue (such as a dnsmasq GUID).  I am seeking
information using the "lctl" command.  The only network on which we
use lustre is Infiniband (ib0).   The Gb TCP network is not in the
initial tuneconf file system creation.

Am I not invoking lctl properly?  (I am using the syntax in the man
page.)  The network is up.  LNET is running.  My "lctl ping
xxx.yyy.zzz.aaa.bbb at ib0" return nicely.   I am trying to gather
information about my network and my lctl commands are informing me
that I need to run the network command before inquiring about
"interface_list".   I do run the network command and I am as yet
unable to get peer_list or conn_list information as lctl indicates
that "network" was not run.  Am I missing something in lctl command
usage?

Thanks,
megan


[root at mds1 ~]# lctl network ib0 up
Can't parse net ib0
[root at mds1 ~]# lctl interface_list
You must run the 'network' command before 'interface_list'.
[root at mds1 ~]# lctl network
usage: network <net>|up|down
[root at mds1 ~]# lctl network up
LNET configured
[root at mds1 ~]# lctl interface_list
You must run the 'network' command before 'interface_list'.
