This section contains the information you need to plan your HA for Logical Domains installation and configuration.
The configuration restrictions in the subsections that follow apply only to HA for Logical Domains.
For restrictions that apply to all data services, see the Oracle Solaris Cluster 3.3 Release Notes.
Caution - Your data service configuration might not be supported if you do not observe these restrictions. |
Restriction for the HA for Logical Domains configuration
Logical Domains can be configured only as a failover data service and not as a scalable data service.
Restriction for using warm migration with HA for Logical Domains data service
Do not configure the HA for Logical Domains data service with Logical Domains version 1.2 or earlier if you want to use the Logical Domains warm migration feature.
Restriction for the location of HA for Logical Domains virtual disks
Logical Domains disk image file should be placed only in the global file system. The file is exported as a raw disk by the virtual disk server and can be used as an installation disk by the Solaris OS installer on the guest domain.
The following example shows Logical Domains guest domains installed onto a global file system with two guest domain instances (ldg0 and ldg1).
# ls -l /global/ldoms/disks/ total 26926720 -rw------T 1 root root 8589934592 Aug 23 03:31 ldg0.vdisk -rw------T 1 root root 8589934592 Aug 21 02:43 ldg1.vdisk
Note - In the example, the virtual disk for theLogical Domains guest domain instance ldg0 is /global/ldoms/disks/ldg0.vdisk, whereas the virtual disk for Logical Domains guest domain instance ldg1 is /global/ldoms/disks/ldg1.vdisk.
