Hey all. Bit of a grey area here between Veritas and Solaris, and probably
a bit offtopic, but not too far.
We were changing some root disk mirroring (all under SDS) on a V880 running
Solaris 8, and managed to hang the box. Force a break and boot, and now
it hangs during the /etc/rcS.d/S25vxvm-sysboot script, right after it
displays "VxVM starting in boot mode..." and then starts "vxconfigd -m boot"
I can disable the Veritas startup scripts and the machine comes up fine,
but of course without Veritas, which means we don't have access to our
Hitachi disk.
I can run cfgadm -al -o show_FCP_dev and all paths to LUNs show up properly,
with two paths to each. However when I run the Veritas sysboot script, let
it hang, and then CTRL-C it, I see that the second path to the Hitachi LUNs
have all changed to status=failing. When I turn on debugging in the VxVM
script, it tells me that it hangs while opening the path to that second
controller.
The tail of the degug output is:
11/03 21:35:47: DEBUG: Controller 0: Open device /dev/rdsk/c0t6d0s0
11/03 21:35:47: DEBUG: Controller 1: Open device /dev/rdsk/c1t3d0s0
11/03 21:35:47: DEBUG: Controller 2: Open device /dev/rdsk/c2t3d0s0
11/03 21:35:47: DEBUG: Controller 3: Open device
/dev/rdsk/c3t500060E8027A8202d1 s0
11/03 21:35:47: DEBUG: Controller 4: Open device
/dev/rdsk/c4t500060E8027A8212d1 s0
And then it hangs.
Has anyone seen this before? We're partway through a 36-hour data centre
outage, and when it's done, this machine really needs to come back up.
Don't know what other information to provide, other than that we're not
using MPxIO on this system (vxdmp takes care of it all).
Thanks,
Colin
