SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Adding a Similar Disk to Another System
To configure the same or a similar disk on another system, create a command file by using the
OBEYFORM attribute of the INFO DISK command. You can copy this file to another system or add
it to a different configuration file on the current system.
1. Capture the configuration for an existing disk:
-> INFO / OUT LOG / $MAG1, OBEYFORM
== STORAGE - Obeyform Information Magnetic DISK \COMM.$MAG1

2. Optionally edit the resulting log file to specify:
• A unique disk name
• Different slot numbers for PRIMARYLOCATION and MIRRORLOCATION
• Different SAC numbers for PRIMARYSAC and MIRRORSAC if the new locations use
different SACs
For 45xx, M8xxx, and ESS disks, PRIMARYLOCATION and MIRRORLOCATION are the
storage adapter locations instead of disk locations, so the adapter location attributes do
not automatically determine the SAC and DEVICEID attributes. You must make sure that
every path for the new disk differs in some way (group, module, slot, SAC number, or
device ID) from every other path configured to every device on the system.
3. Enter the log file contents either by copying and pasting into an SCF command line or by
using the log file as a command file.
Altering Disk Attribute Values
Use the “ALTER DISK Command” (page 228) to change configured attributes for disks.
