Hi,
After a succesful pilot with Logical Domains using 1.0.3 and Solaris 10 update
5 (127127-11) our company have moved to launch a new project based on this
technology. All has been going well, apart from what appears to be a rather
concerning issue. After a reboot of the control domain by our tools team, I
have noticed the following, which I'm sure is "a bad thing"(tm).
Please can anyone shed light on why I might have the same LDC for 2 separate
logical domains? I have had a search through the release notes and bug list,
but with no luck so far.
Here is the output of "ldm list-bindings -e | grep vdisk | grep primary"
ldom-01 ldom01-vol at primary-vds0 disk at 0 primary 4
ldom-02 ldom02-vol at primary-vds0 disk at 0 primary 24
ldom-03 ldom03-vol at primary-vds0 disk at 0 primary 12
ldom-04 ldom04-vol at primary-vds0 disk at 0 primary 16
ldom-05 ldom05-vol at primary-vds0 disk at 0 primary 20
ldom-06 ldom06-vol at primary-vds0 disk at 0 primary 24
Notice the LDC numbers on the right hand side. Surely 24 should not be reused
for 2 different LDOMs? As I understand it, the LDC channels should be uniquely
allocated, point-to-point connections.
The vdsdevs are zfs zvols, all in one zpool.
# ldm ls -l | grep zvol
primary-vds0 ldom01-vol
/dev/zvol/dsk/ldom-zpool/ldom01-vol
ldom02-vol
/dev/zvol/dsk/ldom-zpool/ldom02-vol
ldom03-vol
/dev/zvol/dsk/ldom-zpool/ldom03-vol
ldom04-vol
/dev/zvol/dsk/ldom-zpool/ldom04-vol
ldom05-vol
/dev/zvol/dsk/ldom-zpool/ldom05-vol
ldom06-vol
/dev/zvol/dsk/ldom-zpool/ldom06-vol
If I stop and unbind all the ldoms, and then rebind them one by one, I get no
issues, no duplicate LDCs:
ldom-01 ldom01-vol at primary-vds0 disk at 0 primary 4
ldom-02 ldom02-vol at primary-vds0 disk at 0 primary 8
ldom-03 ldom03-vol at primary-vds0 disk at 0 primary 12
ldom-04 ldom04-vol at primary-vds0 disk at 0 primary 16
ldom-05 ldom05-vol at primary-vds0 disk at 0 primary 20
ldom-06 ldom06-vol at primary-vds0 disk at 0 primary 24
As a first pass, is there a bug/patch that I am likely to be missing - has
anyone seen anything like this before?
Thanks in advance,
Paul.
