Description
If you configure many guest domains in
a system where 16 BBs compose one
physical partition (PPAR), it takes time to
perform binding for the guest domains.
It takes approximately (the number of
guest domains for which binding has
already been performed + 1) x 6 + 10
seconds to perform binding.
Therefore, if there are no domains for
which binding has been performed, and
binding is performed for the guest
domains one by one through the ldm
bind-domain command, the required
time is obtained by summing the times
taken to perform binding for all of them.
If the guest domain is Oracle Solaris 11.1
and SRU11.1.9 or later is applied to it, or
if the guest domain is Oracle Solaris 10
and 150400-01 or newer is applied to it,
system panic may occur when
conducting live migration or dynamic
reconfiguration of physical partitions.
Messages like the following are output to
the console at the time of starting Oracle
Solaris and the ldoms/ldmd service is put
to maintenance mode.
[Example of the messages]
Jan 20 16:01:37 svc.startd[11]: svc:/ldoms/
ldmd:default: Method "/opt/SUNWldm/
bin/ldmd_start" failed with exit status 96.
Jan 20 16:01:38 svc.startd[11]: ldoms/
ldmd:default misconfigured: transitioned
to maintenance (see 'svcs -xv' for details)
At this time, messages like the following
will be registered to the log file
(/var/svc/log/ldoms-ldmd:default.log) of
the ldoms/ldmd service.
[Example of the messages]
[ Jan 21 20:08:55 Executing start method
("/opt/SUNWldm/bin/ldmd_start"). ]
ldmd cannot communicate with the
hypervisor as the required device does
not exist:
/devices/virtual-devices@100/channel-
devices@200/virtual-channel@0:hvctl
Workaround
This has been improved with SRU11.1.16.
4.0, and patch 150011-03 for Oracle
Solaris 10.
We recommend that you do not
configure the system with a single PPAR
but divide it into multiple PPARs and
then configure guest domains in each
PPAR.
Using the recommended configuration
described above, not only mitigates the
described phenomenon but also helps
improve fault tolerance.
If a virtual network switch (vsw) is
configured, you can reduce the time for
binding by half by setting inter-vnet-link
to off. For notes when inter-vnet-link is
set to off, see Oracle VM Server for SPARC
Administration Guide or Oracle VM Server
for SPARC Release Notes.
It has been modified with SRU11.1.14.5.0
and the Oracle Solaris 10 patch 150400-07.
It has been modified with SRU11.1.19.6.0
and the Oracle Solaris 10 patch 150840-04.
[How to restore]
After confirming that the device file in
question exists, restore the ldoms/ldmd
service using the svcadm(1M) command.
# ls -l
/devices/virtual-devices@100/channel-
devices@200/virtual-channel@0:hvctl
crw------- 1 root sys
Jan 21 20:08 /devices/virtual-devices@
100/channel-devices@200/virtual-
channel@0:hvctl
# svcadm clear ldmd
