Description

Unequal amounts of ILM allocated from cells may cause a system panic.

Symptoms

The system panics when unequal amounts of ILM are allocated from the

cells to the nPartition. In other words, each cell is not providing an equal

amount of ILM to the nPartition. During the booting of the kernel, you may

see the following error message:

Can't allocate mem for pfdats.

Workaround

You can either

• Install a patch that should be available later this year. For updates on

patch availability, please check the IT Resource Center Web site at

http://itrc.hp.com and search the technical knowledge base using the

keyword JAGaf64296.

• Insure that each cell in the nPartition contributes an equal amount of

ILM to the nPartition. You can compute the amount of ILM by

performing the following:

1. In nPars mode, determine the total amount of memory on each cell.

For example, if there are 4 cells, use parstatus to show the amount

of memory on each cell.

# parstatus -c 0 -c 1 -c 2 -c 3 -c 4

2. Using the equation
