Easy Tier Heat Map Transfer Utility operations

After you install the heat map transfer utility, you are ready to start using the utility.

About this task

Use this procedure and examples as guides to help you use the heat map transfer utility commands in your environment.

Procedure

Issue the adddev command to make your primary and secondary DS8870 systems known to the heat map transfer utility.
1. hmtu> adddev -hmc1 9.111.14.48 -user admin -passwd passw0rd -dev IBM.2107-75ZA571
  The following output displays:
```
Date/Time: 2013-03-27 11:20:48 IBM HMTU Version: 7.7.10.207
GUSS00000I The device <id = IBM.2107-75ZA571> was added successfully.
```
2. hmtu> adddev -hmc1 9.111.14.49 -user admin -passwd passw0rd -dev IBM.2107-75ZA181
  The following output displays:
```
Date/Time: 2013-03-27 11:21:49 IBM HMTU Version: 7.7.10.207
GUSS00000I The device <id = IIBM.2107-75ZA181> was added successfully.
```
Issue the manageserver command to start the process of managing your heat map data automatically.
1. hmtu> manageserver -action start
  The following output displays:
```
Date/Time: 2013-03-27 11:23:41 IBM HMTU Version: 7.7.10.207
GUSS00004I The Heat Map Transfer server is started.
```

Issue the lsdev command to check the connection status of your storage systems.

hmtu> lsdev -checkconn

The connection status should display Running:

Date/Time: 2013-03-27 11:24:11 IBM HMTU Version: 7.7.10.207

IBM.2107-75ZA181      9.111.14.49                admin           Running

Issue the showserver command to display when the next heat map data transfer will occur.

The following output displays:

Date/Time: 2013-03-27 11:24:42 IBM HMTU Version: 7.7.10.207
ServerStartTime              2013-03-27 11:23:39

XferInterval(min)            720
NextXferStartTime(Estimated) 2013-03-27 14:25:00

After the first heat map transfer is complete, issue the lshmt command to check the heat map data transfer results.

The following output displays (shown as separate results for space considerations):

Date/Time: 2013-03-27 14:55:15 IBM HMTU Version: 7.7.10.207

Issue the manageserver command to initiate an immediate transfer operation instead of waiting for the next scheduled automatic transfer to occur.
1. hmtu> manageserver -action xfer
  The following output displays:
```
Date/Time: 2013-03-27 14:56:14 IBM HMTU Version: 7.7.10.207
GUSS00005I The Heat Map Transfer is started.
```
  Otherwise, the automatic heat map data transfer is processed, by default, every 12 hours. The showserver command displays the heat map transfer status:
```
Date/Time: 2013-03-27 15:38:29 IBM HMTU Version: 7.7.10.207
ServerStartTime              2013-03-27 11:23:39
ServerRunningStatus          Sleeping
XferInterval(min)            720
NextXferStartTime(Estimated) 2013-03-28 02:30:00
```

Example

Note: The Storage Tier Advisor Tool (STAT), when applied to the secondary DS8870 system, will display the Learning Strategy status as "Base on Remote" (as shown in Figure 1) for the respective replication target volumes.
