z Estimating the Dump-use Area
11.1 Estimating the Dump-use Area
If using Linux in PRIMEQUEST systems, the dump function provided by Linux
distribution (diskdump) is available.
This section explains how to estimate the disk spaces necessary for the use of this
dump function. The explanation is provided with respect to the following items in the
order given:
- Area used to collect dump data
- Area used to save dump data
Area used to collect dump data
When a system becomes faulty, a disk partition (dump device) area exclusively used
for dump collection is required.
A dump device is a device on which the dump function temporarily stores information
on problem occurrences. [
Table 11.1 Areas used to collect dump data] lists the sizes
of the areas required for a dump device.
Table 11.1 Areas used to collect dump data
* If a Linux system is installed on a device managed by PRIMECLUSTER GDS,
change the sadump installation destination to an area that is not managed by
PRIMECLUSTER GDS.
