4.9 Dump Environment Setup (Linux: Red Hat)
Table 4.6 Devices usable as dump devices
A dump device must be prepared for each partition of PRIMEQUEST and cannot be
shared by multiple partitions. It cannot be shared by more than one partition.
4.9.1.2 Allocating a dump saving area
Allocate an area to be used to save the dump. This area is called a dump saving area.
Prepare this area for each partition. Note that this area cannot be shared by more than
one partition. The area to be allocated as a dump saving area differs for each type of
Linux OS.
Confirm the dump saving area.
•
RHEL-AS4 (IPF)
The dump saving area is /var/crash.
Perform the following operation to confirm that this directory exists.
•
RHEL5 (IPF)
Reserve a dedicated partition (example: /dev/sdb2) for the dump saving area and
format it as a file system (example: ext3). Perform the following operation to
confirm that this directory has been created correctly.
To ensure that destruction does not occur during operation, be sure not to mount
the dump saving area.
For Linux (Red Hat), prepare the following empty area as the dump saving area.
