or the lack of virtual memory may result in a failure to collect
debug information. Ensure that your system has a sufficient
paging file size.
■ The maximum paging file size allowed per partition is
4095 MB. If the value of the installed memory size x 1.5
exceeds 4095 MB, set the paging file size to 4095 MB.
■ When the installed memory size exceeds 2GB, the maxi-
mum dump file size 2048MB + 300MB.
■ To install additional applications, add a disk volume for the
applications.
Example:
A partition size required for a system with an installed memory size of 512 MB and a
full installation of the operating system:
6,300MB + (512MB x 1.5) + 512MB + 300MB + application size = 7,880MB +
application size.
If the partition where the operating system is installed is smaller than the sum of
necessary size to install OS and paging file size", expand the partition size or provide a
larger disk. If your system does not have a sufficient dump file size, divide the required
file space into multiple disks by performing the steps below:
1. Set the partition size to the sum of size required to install OS and paging file
size".
2. See “Fault Recovery Settings”, page 30 to write the debug information of the
dump file into another disk.
If there is not enough disk space to write the debug information, add another disk for
Dump file.
