To all Alternate I/O domain Gurus,
I have an alternate i/o domain setup on one of my T2000 box.
I am stuck at the point where only one boot disk of the guest
shows up inside the guest and not the other.
>From the control domain:
# ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv SP 4 4G 0.8% 1d 3h 24m
alternate active -n--v 5000 4 4G 0.6% 22h 31m
ldom1 active -n--- 5001 4 4G 0.5% 23m
guest domain bindings:
# ldm list-bindings ldom1 | grep vds0
vdisk1 vdisk1 at primary-vds0 disk at 0 primary
vdisk2 vdisk1 at alternate-vds0 disk at 1 alternate
# /opt/SUNWldm/bin/ldm list-services primary
VDS
NAME VOLUME OPTIONS DEVICE
primary-vds0 vdisk1 /fsmnt1/ldom1_boot.img
# /opt/SUNWldm/bin/ldm list-services alternate
VDS
NAME VOLUME OPTIONS DEVICE
alternate-vds0 vdisk1 /fsmnt1/ldom1_boot.img
Inside the guest I see only: one disk: c0d1:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d1 <SUNVDSK cyl 22717 alt 2 hd 1 sec 600>
/virtual-devices at 100/channel-devices at 200/disk at 1
Specify disk (enter its number)
Both the files are accessible from both the i/o domains:
primary # ls -l /fsmnt1/ldom1_boot.img
-rw------T 1 root root 6979321856 Jan 10 17:06 /fsmnt1/ldom1_boot.img
alternate # ls -l /fsmnt1/ldom1_boot.img
-rw------T 1 root root 6979321856 Jan 10 17:11 /fsmnt1/ldom1_boot.img
Also, from the ok prompt of the guest, I can see 2 disks attached to it:
a) /virtual-devices at 100/channel-devices at 200/disk at 1 <-- this one is
visible inside the guest as c0d1
b) /virtual-devices at 100/channel-devices at 200/disk at 0 <-- this one is not
visible, should have showed up as "c0d0"
"c0d1" visible inside the guest is the backed by the file exported
from the alternate i/o domain.
but the other disk backed by the file exported from the primary i/o
domain is not visible.
Any idea what may be going wrong here?
Thanks,
Misha.
