About cluster listing tables

The following is a list of the columns and data in tables that list cluster information. These tables are usually labeled Clusters Listing, but may have more detailed labels at lower view levels.

• Cluster - Indicates the name of the cluster and a link to the Cluster:Summary view for the cluster
• Status - Indicates the consolidated state of the cluster

  See Object states and consolidated states.

• Groups - Indicates the number of groups in the cluster
• Systems - Indicates the number of systems in the cluster
• Cluster Type - indicates the clustering software used to implement the cluster (this value is VCS for VCS clusters)
• Cluster Version - Indicates the version of the clustering software used to implement the cluster
• Platform - Indicates the operating system platforms in the cluster
• Region - Indicates the region or area that cluster services resides (You can define the region tag)
• Site - Indicates the site or location where cluster resides. (You can define the tag)

  See Editing tags of selected clusters for more information.

• Management Server - Indicates the name of the management server to which the cluster belongs

A cluster listing table can appear on more than one view, but the Management Server column is omitted if you have already visited that object level. For example, to reach a particular view containing a cluster listing table, you may have already navigated through one view level by selecting a particular management server. In this case, the column that shows the management server that you have already visited is not included. However, the navigation bar always contains this information.

Using filtering, sorting, and the navigation path

You can tailor a cluster listing table according to your needs by doing one or more of the following:

• Filter - Filter the list of clusters to reduce it to those of current interest to you.
• Sort - Sort the list by the values in a column.
• Move up the navigation bar - Click the navigation bar links to see more clusters from a higher position within the view hierarchy.

 To filter clusters

1. In the either the Home:Clusters or Management Server:Clusters view, under the Cluster Filter panel in the task pane, do any of the following:
   • To view only the clusters that are in certain states, under By Consolidated State, select the states you want (one or more) by checking the check boxes next to Online, Offline, Coming Up, or Unknown.
   • To view only the clusters of one platform, select the platform you want in the By Platform drop-down menu.
   • To view only the clusters in one region, select the region you want in the By Region drop-down menu.
   • To view only the clusters of one site, select the site you want in the By Site drop-down menu (this filter uses the Site tag).
2. Click Apply.

 To sort clusters

1. In the Clusters Listing table, locate the column by which you want to sort the list.
2. Click the column heading.

   The list is sorted by the values in the selected column in ascending order. An arrow (pointing up) displays in that column heading. Click the column heading again to reverse the sort; this action also reverses the arrow.

Command line tips

You can view cluster information using the command line.

 To view a list of clusters at the home level using the command line

• gaclus -list

 To view cluster attributes at the cluster level using the command line
