Hi gurus,
just a question concerning SC 3.1 and the good ol' D1000: Are these
old-fashioned storages still supported in an SC 3.1U4/Sol. 10
environment?
I have the following setup here (just for testing purposes, so I decided
to re-use some old systems and storages we had in stock):
2 E420, each equipped with a qfe-card for cluster interconn and a
SCSI-Hostadapter to connect them to the shared storage, which is an old
JBOD D1000 with two 36GB disks.
Now the problem: I've set the SCSI initiator ID as described in the
appropriate infodoc, and I can see all disks on both nodes when I issue
a probe-scsi-all simultaneously on both nodes.
So, SCSI driver should be happy, but when I try to register the devices
using devfsadm, the systems hang and only a reboot helps to get them
working again. When I attach the storage to only one of the nodes (no
matter to which one), everything's fine, and I can see the disks, format
them, mount them, etc.
So, I'm a little bit confused, as I did use such a setup very often in
the past with SC3.1 / Sol. 9 without any problems, and my clue is that
it's somehow no longer supported in a Sol. 10 environment.
Can anyone confirm this? Or, has someone of you even done such a setup
successfully?
It's more or less an academic question, since the real environment will
be different (of course, I don't like to use these JBODs any more), and
for my test, I've thrown away one of the nodes and will now do my test
on a single-node cluster - but, I'm interested in your experiences...
Thanks, will (of course) summarize,
Harald
