Client recovery scenario

The following scenario demonstrates the recovery of clients.

1. To view a list of client machines that were lost in building 21 and their restore priority, issue the following command:

   query machine building=021 format=detailed

   DRM displays information similar to the following:

             Machine Name: POLARIS
         Machine Priority: 1
                 Building: 21
                    Floor: 2
                     Room: 1
                  Server?: No
              Description: Payroll
                Node Name: POLARIS
      Recovery Media Name: MKSYSB1
         Characteristics?: Yes
   Recovery Instructions?: Yes

   Identify which client machines have the highest priority so that restores can begin using active-data pool volumes.
2. For each machine, issue the following commands:
   1. Determine the location of the boot media. For example:

      query recoverymedia mksysb1

      The server displays the following information:

      Recovery Media Name  Volume Names    Location    Machine Name
      -------------------- -----------     ----------  ----------------
      MKSYSB1              vol1 vol2       IRONVAULT    POLARIS
                            vol3

   2. Determine the machine-specific recovery instructions. For example:

      query machine polaris format=recoveryinstructions

      The server displays the following:

      Recovery Instructions for Polaris.
      Primary Contact:
         Jane Smith (wk 520-000-0000 hm 520-001-0001)
      Secondary Contact:
         John Adams (wk 520-000-0001 hm 520-002-0002)

   3. Determine the machine hardware requirements.

      query machine polaris format=characteristics

      The server displays information similar to the following:

3. With the information obtained, restore each client machine.

   Once the high-priority clients have begun restoring their data from active-data pools, the other, lower-priority clients can begin restoring directly from copy storage pools. Restoration from copy storage pools can run concurrently with the restoration from active-data pools. High-priority clients do not attempt to access the copy storage pool volumes because active-data pools have a higher restore priority than copy storage pools.
