esssnap script

Collects the snapshot of the IBM Storage Scale System deployment

Synopsis


esssnap [ -N |  NodeList ] [ --skip-gpfs ] 
        [ --dir |  OutputDirectory ] [ -h | --help ]  

Availability

Available with IBM Storage Scale System.
Remember: For the esssnap command to run successfully, the container must be in running state.

Description

The esssnap script creates an informational system snapshot at a single point in time. This system snapshot consists of cluster configuration, disk configuration, network configuration, network status, IBM Storage Scale System logs, dumps, and traces. Use the esssnap script as one of the main tools to gather preliminary data when an IBM Storage Scale System problem is encountered, such as a hung IBM Storage Scale System script. The information that is gathered with the esssnap script can be used in conjunction with other information (for example, ESS internal dumps, traces, and kernel thread dumps) to solve an IBM Storage Scale System problem.

Parameters

-h | --help
Displays usage information about this script and exits.
-N NodeList
Specifies a comma-separated list of nodes from which to collect snapshot information.
--skip-gpfs
Skips gpfs.snap and saves only IBM Storage Scale System information.
--dir OutputDirectory
Specifies output directory name. The default output directory is /var/mp/.

Exit status

0
Successful completion.
nonzero
A failure has occurred.

Security

You must have root authority to run the esssnap script.

Example

Collects a snapshot on an I/O node gssio1.
esssnap -N gssio1
Note: You must include the management server when you take a snapshot on an IBM Storage Scale System.
