Dump Initialization - NEC Express5800 Series User Manual

3-12 Linux Setup and Operation

DUMP INITIALIZATION

1. Checking partition for diskdump
1-1. Check /var/crash (Dump file storage area)
# df
Filesystem 1K-blocks
/dev/md1 40313912
/dev/md0
none 1035356
/dev/md3 10080364
Note: Unless you have created /var/crash partition, it does not exist. The dump file
will be created on the partition that the root file system exists.
1-2. Check diskdump partition (Dump file creation area)
#fdisk /dev/md*
Run "p print the partition table."
When HAS is loaded, run it at "fdisk /dev/had*."
*
Check that dump partitions exist as many as the disks in fdisk.
*
Device Boot
/dev/hada1
/dev/hada2
/dev/hada3
/dev/hada4
/dev/hada5
/dev/hada6
Check the partition which is created for diskdump and the ID is 83.
In this example hada6 is the dump partition.
Note: If 1-1 and 1-2 do not exist, reinstall the OS. Create a dump partition in the
phase of partition creation during installation.
2. Initializing the diskdump partition
2-1. Edit /etc/sysconfig/diskdump
Open the file in:
#vi /etc/sysconfig/diskdump
and then add:
DEVICE=/dev/hada6:/dev/hadb6
and comment out other lines.
For had*, specify the value of the partition you checked in 1-2.
Even when the disk is expanded, this file needs to be edited.
