LDT GuardPoint Group Commands

Please Note:

LDT GuardPoint Group Commands

Prerequisites for CIFS Share drives

Prior to running the voradmin ldt group commands, you must:

  1. Ensure that you have access and permission to read/write to/from the CIFS share.

  2. Mount the CIFS share using the net use command, or login to the CIFS shares using Windows Explorer.

Group check

The group check command is used to send out an internal ping to all hosts that are registered with the master as part of the LDT Communication Group. Each functioning host responds. Then the host displays a message of the hosts in the LDT Communication Group that did not respond. This allows an administrator to easily find the problem.

Syntax

voradmin ldt group check <gp_path>

Example (Windows)

voradmin ldt group check \\192.168.1.160\share

Hostname             Role         State      GuardPoint Path
192.168.1.161        PRIMARY      JOINED     \\192.168.1.160\share
192.168.1.162        SECONDARY    JOINED     \\192.168.1.160\share

Example (Linux)

voradmin ldt group check /nfs1/gp

Role              State     Hostname         GuardPoint Path
PRIMARY           JOINED    host1.domain     /nfs1/gp1
SECONDARY         JOINED    host2.domain     /nfs1/gp1

Info

Use the info command to display information about the cluster.

Syntax

voradmin ldt group comm_info <gp_path>

Example (Windows)

voradmin ldt group comm_info \\192.168.1.160

LDT Communication Group Master IP:       10.171.34.111
LDT Communication Group Master Port:     7024
LDT Communication Group Name:            tanmay_windows
LDT Communication Group Servers:         10.171.34.111,10.171.34.120,10.171.34.119

Example (Linux)

voradmin ldt group comm_info /nfs1/gp1

LDT Communication Group Name:           tanmay-linux
LDT Communication Group Master IP:      10.171.47.121
LDT Communication Group Master Port:    7024
LDT Communication Group Servers:        10.171.47.241,10.171.47.121,10.171.47.75

Remove

This command allows a client to be manually removed from the group safely. Use the Remove Host command if a client dies without properly leaving the group.

Note

Only run this command on clients which will be powered off. Do not run it on a client which may simply have temporary network issues.

Syntax

voradmin ldt group remove <hostname> <GuardPoint pathname>

Example (Windows)

voradmin ldt group remove host42 \\server\share

WARNING: This command will forcibly remove host42 from the LDT group for gp_path
You should only perform this step if the host is guaranteed to be powered off, otherwise a
loss of data may result.  Do you wish to continue? (Y/N)

Example (Linux)

voradmin ldt group remove host2 /nfs-ldt

host2 has been removed from the group for GuardPoint /nfs-ldt
