Reconfiguring a Storage System
The following explains how to reconfigure a storage chassis in these ways:
• Changing physical disk configurations
• Changing physical disk unit parameters
• Updating Licensed Internal Code
The procedures below assume you are using DASSMGR to reconfigure the storage
chassis.
Changing Physical Disk Configurations
As your organization’s needs change, you may want to add disk modules to any
unused compartments (slots).
Adding Disk Modules and Creating New Logical Units
If the storage chassis has unused disk module slots, you can increase the available
storage capacity by installing additional disk modules, as described in “Replacing or
Adding a Disk Module” on page 18. Normal processing can continue while you
install disk modules.
IMPORTANT All disk modules in any one storage chassis and in any
storage chassis in chains must be of the same capacity.
We recommend that you add disk modules in groups of five to the slots in the
following order:
A0, B0, C0, D0, E0,
A1, B1, C1, D1, E1,
A2, B2, C2, D2, E2,
A3, B3, C3, D3, E3
To add a physical disk unit:
1. Update the worksheets that define your configuration.
2. Remove the disk filler modules and install the additional disk modules. Refer to
“Upgrade and Repair of a Storage System” on page 14 for instructions.
3. Bind the newly installed disk modules into the desired logical unit. See “Binding
Disk Modules as a Logical Unit” on page 6.
4. Refer to your Profile User Manual to make the newly created physical disks
available to the Profile operating system.
