About this task

Use the following information to modify an existing IBM Storage Protect Snapshot profile and reconfigure the product to SVCDTA.

Procedure

To start the configuration process, run the setup script.
Choose (m) to modify the profile.
Change the value of COPYSERVICES_HARDWARE_TYPE from SVC to SVCDTA.
If MAX_VERSIONS is set to ADAPTIVE, you must return to the CLIENT section, and change the MAX_VERSIONS parameter from ADAPTIVE to a fixed number.
Enter the existing server information for the storage system host name COPYSERVICES_SERVERNAME<TCP/IP host name>.
Enter the user name for the primary storage device COPYSERVICES_USERNAME.
The default value is superuser.
Enter the path and the file name of the private SSH key file in parameter SVC_SSHKEY_FULLPATH.
For example,
```
SVC_SSHKEY_FULLPATH    $HOME/.ssh/svc_sshkey
```
Accept the defaults for the remaining parameters, or change the values where required.

Note: Do not change the FlashCopy® type.

Results

The updated profile is saved, and if required you can specify a backup system or quit the configuration.IBM Storage Protect Snapshot for UNIX and Linux is configured to use the SAN Volume Controller storage adapter with dynamic target allocation.

After reconfiguring the profile for SVCDTA, all backups are managed by the new dynamic target allocation adapter, including all backups that were taken with the CIM adapter. Continue to mount, restore, delete, and expire backups as usual. When FLASHCOPY_TYPE is set to INCR, you can also refresh backups as required.
