How do you make a concurrent VG in Hacmp?

To create a concurrent volume group for a selected list of cluster nodes:

  1. From the command line, enter smit cspoc .
  2. In SMIT, select Storage > Volume Groups > Create a Volume Group (or Create a Volume Group with Data Path Devices) and press Enter.
  3. Select one or more nodes from the list of cluster nodes and press Enter.

How do I check my Hacmp cluster status?

Depending on what you need to know, you may access the following for information:

  1. View Management Information Base (MIB)
  2. Look for cluster events and errors in the hacmp. out file.
  3. Use SMIT to check the status of the following PowerHA SystemMirror subsystems on a node: Cluster Manager ( clstrmgrES ) subsystem.

What is cluster St_init?

ST_INIT: cluster is configured but not active on this node. ST_JOINING: cluster node is joining the cluster. ST_VOTING: cluster nodes are voting to decide event execution. ST_RP_RUNNING: cluster is running a recovery program. RP_FAILED: recovery program event script is failed.

What is concurrent VG in AIX?

In concurrent access, the volume groups residing on shared disks are activated and can be simultaneously accessed in read/write mode by all active nodes in the cluster. Note: AIX® introduced enhanced concurrent mode.

How do I add a disk to Hacmp cluster?

8 Answers

  1. Run cfgmgr on both nodes.
  2. Add disk to primary node and run varyonvg -b -u
  3. On secondary node run importvg -L should not be the newly added disk.
  4. varyonvg on primary node.

How do you convert normal VG to Big VG?

MiniTip: Convert a Standard VG to Big VG Format

  1. Introduction. For new volume groups I strongly recommend to only use scalable VGs with a physical partition size of 32.
  2. Convert to Big VG Format. To convert a standard VG to big VG format every physical volume in the volume group needs at least one free physical partiton.

How do I start Hacmp cluster services?

Select System Management (C-SPOC)] >> Manage HACMP Services >> Start Cluster Services. In the Start Cluster Services window, enter the field values for nodes on which cluster services are started.

What does inertia K mean?

K-Means: Inertia Inertia measures how well a dataset was clustered by K-Means. It is calculated by measuring the distance between each data point and its centroid, squaring this distance, and summing these squares across one cluster. A good model is one with low inertia AND a low number of clusters ( K ).

How do I check my Hacmp log?

You can view the hacmp. out log file in HTML format by setting formatting options on the Problem Determination Tools > PowerHA SystemMirror Log Viewing and Management > Change/Show PowerHA SystemMirror Log File Parameters SMIT panel.
