Configure the Basic ARM

To configure the Auto Restore Manager (ARM):

Use the Config Client to specify the appropriate system parameters.
The appropriate system parameters for ARM are available in the Config Client directory: Configure GMI Qualified Products, CA Disk, Auto Restore Manager.
Activate the Receiver-Dispatcher components.
Uncomment the following statements in the CONFIG member of your PARMLIB, but do not change their order.
```
*COMP=RCDSP UNCOMMENT IF ARM/ALLOMGR USED (SUARH=Y OR SUPLS=Y) 
*COMP=ARM UNCOMMENT IF ARM IS USED (SUARH=Y) 
```
When the above steps are completed, the Receiver-Dispatcher components and ARM will automatically be started when CA Vantage GMI (SAMS) is started on the host.

Note: If you uncomment the COMP=ARM statement but fail to uncomment the COMP=RCDSP, auto restores will fail because the requests cannot be received, and a soft loop will occur at system shutdown, issuing the following message:
```
VAN0902I Comp=ARM Shutdown in Progress. Waiting for Normal Completion or Forced Termination. 
```
Activate and Manage ARM.
ARM is automatically started as part of SAMS startup if the two steps above have been completed. If you want to restart SAMS now, use the following commands:
```
F SAMS,STOP (to shut SAMS down) 
S SAMS (to start SAMS up again)
```
After ARM is up, perform the following procedures to manage its activity for special needs:

To Suspend or Resume ARM

The SUSPEND command suspends ARM processing of requests for a short period of time and frees the FILES data sets such that CA Disk IXMAINT jobs can perform maintenance. When this is needed, issue the command:
```
F SAMS,ARM,SUSPEND 
```
When maintenance is finished, the RESUME command causes CA Vantage GMI to reallocate the FILES and resume processing of queued/pending restore requests. To resume ARM processing, issue:
```
F SAMS,ARM,RESUME 
```
To Deactivate or Activate ARM

To deactivate ARM for a short period of time, issue the command:
```
F SAMS,ARM,DRAIN 
```
To reactivate it again (after being drained), issue the command:
```
F SAMS,ARM,START 
```
To deactivate ARM permanently:

Specify system parameter SUARH (N) and then stop and restart SAMS. That is, issue the commands:
```
F SAMS,STOP (to shut the system down) 
S SAMS (to start it up again) 
```
Identify ARM to CA Disk.
If ARM is to be used, CA Disk must know this and be able to identify the appropriate system. To inform

CA Disk that ARM is to be used, do the following:
1. In the CA Disk PARMLIB, set system parameter SAMSYSNM to the name of the CA Vantage GMI subsystem.
  That is, ensure that the CA Disk system parameter SAMSYSNM has the same value as CA Vantage GMI system parameter SUBSYSN. The CA Vantage GMI default value is (SAMS). Because the name must be four characters long, use quotation marks if the last character is a blank.
2. To identify the subsystem to the CA Disk catalog management hook, do the following:
  If the CA Disk auto restore hook is already active then issue the commands:
  
  S DMSAR,DMSAR=REMOVE
  
  S DMSAR,DMSAR=INSTALL
  
  If the CA Disk auto restore hook is not already active then issue the command:
  
  S DMSAR,DMSAR=INSTALL

The basic ARM is activated, configured, and identified to CA Disk.
