Disk Access Failed while Installing Solaris Container.

Question

I have setup 5 guest domains together with the Control Domain.
$ ldm list
Name State Flags Cons VCPU Memory Util Uptime
primary active -t-cv SP 4 4G 0.8% 2d 2h 15m
secondary active -t--v 5000 4 2G 0.5% 3h 5m
dmz active -t--- 5001 8 2G 0.0% 46m
sunray inactive -----
application inactive -----
identity active -t--- 5002 4 4G 0.1% 1h 2m
In each of the guest domain, I plan to install a number of Solaris Containers to run different applications. While installing one Solaris container (zoneadm �z <zone name> install) in dmz domain, I start the installation/configuration (either zoneadm �z <zone name> install or zlogin �C <zone name>) of another Solaris container in identity domain. Everything starts OK until half way I get an error message as follow:
Jun 13 18:33:16 dmz vdc: NOTICE: [1] disk access failed.
The installation of the Solaris Container in dmz halts as soon as I see the message above. Nothing will work except a force stop in the Control Domain using ldm stop �f dmz and restart.
What happen to the Solaris Container installation/configuration in identity domain? It either continues the process without error or fails with the same error message shortly after. For example,
Jun 13 18:33:24 identity vdc: NOTICE: [1] disk access failed.
The vdisks for each guest domain are setup by following the steps on section �Using ZFS Over a Virtual Disk� in LDoms 1.0 Administration Guide. Each guest domain is booted from a disk image in the Control Domain and has two 9GB data vdisks (mapped to two physical 9GB disks on A5200 disk array) running ZFS striping. Each guest domain vdisks are serviced by a separate vdisk server.
Any idea?

Answer 1

I am not sure if multiple virtual disk servers are officially supported under current LDoms release.
I had tried using only one virtual disk server. The same problem exhibited. I thought may be the vds was not able to keep up with the virtual disk I/O. That's why I setup multiple vds.
