Hello,
I have a problem with getting multipath support working. I have a Sun
Fire V240 connected with a SG-XPCI2FC-QF2 through a Brocade SAN to a HP
EVA 5000. The V240 is running Solaris 9 ("SunOS 5.9 Generic 118558-14
Sep 2005").
I have configured /kernel/drv/scsi_vhci.conf with
mpxio-disable="no";
device-type-scsi-options-list = "COMPAQ HSV110 (C)COMPAQ", "symmetric-option";
symmetric-option = 0x1000000;
and the four paths per LUN which were initially visible have been
replaced by a (presumably) multipath-aware device per LUN.
"luxadm probe" reports:
Found Fibre Channel device(s):
Node WWN:50001fe100152b80 Device Type:Disk device
Logical Path:/dev/rdsk/c8t600508B40001412800014000000F0000d0s2
Node WWN:50001fe100152b80 Device Type:Disk device
Logical Path:/dev/rdsk/c8t600508B4000141280001400000120000d0s2
which is as expected, the EVA has 2 disks presented to this host. But
when I try to access disks devices with format, it doesn't recognize a
disk type; auto-configure fails. If I follow the instructions near the
top of ftp://ftp.cs.toronto.edu/pub/jdd/sunmanagers/format.dat to
manually set an approximately-correct disk type, then writing a label
results in:
Warning: error writing VTOC.
Not ready error during read
ASC: 0x4 ASCQ: 0x2
"luxadm start" and "luxadm -e online" haven't improved things.
I'm not using Secure Path (I'd understood that mpxio was sufficient) yet
I can't see what's wrong here. I'm comfortable with the HP/Brocade side
of this setup, but my Sun knowledge is minimal... this problem has been
kind of dropped on me. :-) Help, please? I'll summarise replies.
Thanks,
Dave Holland
