cpdumps

Use the cpdumps command to copy dump files from a nonconfiguration node onto the configuration node.

Note: In the rare event that the /dumps directory on the configuration node is full, the copy action ends when the directory is full and provides no indicator of a failure. Therefore, clear the /dumps directory after migrating data from the configuration node.

Syntax

cpdumps -prefix { directory | file_filter } { node_name | node_id }

Parameters

-prefixdirectory | file_filter

(Required) Specifies the directory, or files, or both to be retrieved. If a directory is specified with no file filter, all relevant memory dump or log files in that directory are retrieved. You can use the following directory arguments (filters):

/dumps (retrieves all files in all subdirectories).
/dumps/audit
/dumps/cimom
/dumps/cloud
/dumps/configs
/dumps/elogs
/dumps/easytier
/dumps/enclosure
/dumps/feature
/dumps/iostats
/dumps/iotrace
/dumps/mdisk
/home/admin/update

In addition to the directory, you can specify a file filter. For example, if you specified /dumps/elogs/*.txt, all files in the /dumps/elogs directory that end in .txt are copied.

Note: The following rules apply to the use of wildcards with the CLI:

The wildcard character is an asterisk (*).
The command can contain a maximum of one wildcard.
When you use a wildcard, you must surround the filter entry with double quotation marks (""), as follows:
```
>cleardumps -prefix "/dumps/elogs/*.txt"
```

node_id | node_name

(Required) Specifies the node from which to retrieve the memory dumps. The variable that follows the parameter can be one of the following:

The node name, or label that you assigned when you added the node to the system.
The node ID that is assigned to the node (not the worldwide node name).

If the node specified is the current configuration node, no file is copied.

Description

This command copies any memory dumps that match the directory or file criteria from the given node to the current configuration node.

You can retrieve memory dumps that were saved to an old configuration node. During failover processing from the old configuration node to another node, the memory dumps that were on the old configuration node are not automatically copied. Because access from the CLI is only provided to the configuration node, system files can only be copied from the configuration node. This command enables you to retrieve files and place them on the configuration node so that you can then copy them.

You can view the contents of the directories by using the lsdumps command. You can track the status of a copy using the lscopystatus command.
