Installing an Air Management Module

An air management module looks like a drive module; however, it is an empty box

used to maintain optimum airflow and proper cooling in an enclosure. If your

system was ordered with less than 12 drive modules it was shipped with air

management modules for the slots without drive modules. Optionally, air

management modules can be ordered.

If you must remove a drive module and cannot immediately replace it, you must

leave the faulty drive module in place, or insert an air management module to

maintain the optimum airflow inside the chassis. The blank is installed using the

same procedure as "Installing a Drive Module" on page 107.

Obvious virtual disk problems involve the failure of a member disk drive. However,

there are a number of not so obvious issues that result in virtual disk faults as seen

in Table 7-6.

Solution

• In general, expanding a virtual disk can take days to complete.

You cannot stop the expansion once it is started.

• If you have an immediate need, create a new virtual disk of the

size you want, transfer your data to the new virtual disk, and

delete the old virtual disk.
