Hi Megan,
Thanks - yes, lctl ping responds.
In the end, we did a writeconf, and this seems to have fixed the problem,
so probably some previous transient. I would however have expected it to
heal whilst online - taking the filesystem down and doing a writeconf
seems a bit drastic!
Cheers,
Alastair.

Hi!
Does the NIC on the OSS that serves OST 4-7 respond to an lctl ping?
You indicated that it does respond to regular ping, ssh, etc. I would
review my /etc/lnet.conf file for the behavior of a NIC that times out.
Does the conf allow for asymmetrical routing? (Is that what you wish?)
Is there only one path to those OSTs or is there a way failover NIC
address that did not work in this even for some reason?
The Lustre Operations Manual Section 9.1 on lnetctl command shows how you can
get more info on the NIC ( lnetctl show...)
Good luck.
