Test IP Addresses

The test IP addresses that you supply must meet the following requirements:

• Test IP addresses for all adapters in the same multipathing group must belong to a single IP subnet.

• Test IP addresses must not be used by normal applications because the test IP addresses are not highly available.

The following table lists each metaset name and cluster-file-system mount point that is created by SunPlex Installer. The number of metasets and mount points that SunPlex Installer creates depends on the number of shared disks that are connected to the node. For example, if a node is connected to four shared disks, SunPlex Installer creates the mirror-1 and mirror-2 metasets. However, SunPlex Installer does not create the mirror-3 metaset, because the node does not have enough shared disks to create a third metaset.

Table 2–5 Metasets Installed by SunPlex Installer

Shared Disks	Metaset Name	Cluster File System Mount Point	Purpose
First pair	mirror-1	/global/mirror-1	Sun Cluster HA for NFS or Sun Cluster HA for Apache scalable data service, or both
Second pair	mirror-2	/global/mirror-2	Unused
Third pair	mirror-3	/global/mirror-3	Unused

Note –

If the cluster does not meet the minimum shared-disk requirement, SunPlex Installer still installs the Solstice DiskSuite packages. However, without sufficient shared disks, SunPlex Installer cannot configure the metasets, metadevices, or volumes. SunPlex Installer then cannot configure the cluster file systems that are needed to create instances of the data service.
