Setting up your disk configuration after installing the Licensed Internal Code

Perform these steps to set up your disk configuration after installing the Licensed Internal Code and initializing the system.

When you install the Licensed Internal Code by using option 2 from the Install Licensed Internal Code (LIC) menu, the system does the following tasks:

The system clears disk unit 1. Disk unit 1 contains information about how all the other disk units on your system are configured. If you are using logical partitioning, disk unit 1 also contains your partitioning configuration data.
The system prepares to delete all data in the system auxiliary storage pool (ASP). The system ASP is not actually cleared until you perform the initial program load (IPL) after installing the Licensed Internal Code.

When you complete installing the Licensed Internal Code, you are shown the Disk Configuration Attention Report display on the A or B mode IPL:

                   Disk Configuration Attention Report
 
Type option, press Enter
  5=Display Detailed Report
 
OPT    Warning
___    New disk configuration

If you type a 5 in the option column (OPT), you are shown the following display:

The current configuration indicates a single unit system. You
can choose to accept it or do one of the following:
 
Following are the possible causes and recovery procedures:
 
• You can define a new configuration by adding units.
 
• Press F3 to exit to dedicated service tools (DST) and if
necessary, take the right option to get to
'Use DST' display.
On the 'Use DST' display,
- Select option 4, Work with disk units.
- Select option 1, Work with disk configuration.
- Select option 3, Work with ASP configuration.
- Select option 3, Add units to ASPs.
 
• If you are performing 'Recover mirror load source'
utility, press F3 to exit to Dedicated Service Tools (DST).
If necessary, take the right option to get to 'UseDedicated Service Tools
 (DST)' display.
On the 'Use Dedicated Service Tools (DST)' display,
- Select option 4, Work with disk units.
- Select option 2, Work with disk unit recovery.
- Select option 16, Recover mirrored load source.
 
Press Enter to accept the current configuration and continue.

Press F10 or Enter to accept the new disk configuration and continue.
Perform the following steps:
1. Initialize all of the non-load source disk units on your system.
2. Define which ASP each disk unit is configured in.
3. Determine which ASPs to start mirrored protection on.
See Checklist 1: Configuring disks on a new system for a checklist on adding disk units to the system ASP, adding disk units to the user ASPs, starting mirrored protection on ASPs, and starting device parity protection. When you have completed the checklist, press F12 to cancel the DST menu. You are shown the IPL or Install the System menu.

You have now completed your disk configuration. Continue with the next step on your recovery checklist, which is restoring the operating system.
