CHAPTER 4 Work Required After Operating System Installation
4.9 Dump Environment Setup (Linux: Red Hat)
When the dump function is used under Linux (Red Hat) control, disk space must be
allocated in advance. For information on how to allocate the area, see the
PRIMEQUEST 580A/540A/580/540/480/440 System Design Guide (C122-B001EN)
or PRIMEQUEST 520A/520/420 System Design Guide (C122-B009EN).
When Linux (Red Hat) is used with PRIMEQUEST, the dump function that can be
used depends on the Linux OS version. The following briefly explains the dump
environment for each Linux OS version.
RHEL-AS4 (IPF)
When RHEL-AS4 (IPF) is used with PRIMEQUEST, the dump function (diskdump)
provided by the Linux distribution and the dump function (sadump) dedicated to
PRIMEQUEST can be used.
