Setup when mass memory is installed
If mass memory is installed in your system, the large size of paging file is required at installation,
and the partition size for storing debug information (dump file) cannot be allocated.
If you fail to create the partition, allocate the required size to multiple disks according to the
following steps.
1. Set the system partition size to a size sufficient to install the OS and paging file.
2. Specify another disk as the destination to save the debug information (required dump file
size) according to Chapter 1 (4. Setting up for Maintenance).
If the hard disk drive does not have enough free area to write the debug information, set the
partition size to a size sufficient to install the OS and paging file, and then add another hard disk
drive for the dump file.
Note
If the partition size for installing Windows is smaller than the recommended
size, expand the partition size or add another hard disk drive.
If sufficient free area cannot be allocated for the paging file, perform either of the following after
install Windows.
Specify a hard disk drive other than the system drive as the location to store
the paging file for collecting memory dump
Create a paging file of "installed memory size + 400 MB (installed memory size + 1,100 MB
when the size is 4 TB or more)" or more in a drive other than the system drive.
The paging file that exists in the first drive (in the order of drive letter C, D, E, ...) is used
as the temporary memory dump location.
Therefore, make sure that the size of the paging file that exists in the first drive is at
least "installed memory size + 400 MB (installed memory size + 1,100 MB when the
installed physical memory is 4 TB or more)".
Paging files in dynamic volumes are not used for dumping memory. The setting is
applied after restarting the system.
Example of correct setting
C : No paging file exists
D : Paging file whose size is "installed memory size + 400 MB* " or more
→ The paging file in drive D can be used for collecting memory dump
because its size satisfies the requirement.
