Chapter 4. System Preparation
This section covers the steps that must be taken to appropriately prepare your system for installation
and configuration of HPSS and its infrastructure.
•
General setup (Section 4.1)
•
Setup filesystems (Section 4.2)
•
Setup tape libraries (Section 4.3)
•
Verify tape drives (Section 4.4)
•
Setup disk drives (Section 4.5)
•
Setup network parameters (Section 4.6)
To understand and optimize the operation of HPSS, some baseline measurement,
evaluation, and tuning of the underlying network and IO subsystems is necessary.
Appropriate tuning of these components is necessary for HPSS to perform as
expected. Any one component that is not performing at its optimal rate will have an adverse
affect on the performance of the entire system. The steps and tools listed in this chapter will
help a site make the best use of their available resources. The measurements taken should be
saved for future reference. If performance problems occur later on, these values can be
compared with new measurements to determine if the performance problems are related to
changes in the subsystems. Though disk and tape configurations rarely change without an
administrator's knowledge, networks can “mysteriously” degrade for a variety of reasons.
This is especially true for client access to the HPSS system.
4.1. General Setup
•
Each HPSS administrator should request a login id and password for the IBM HPSS web site
at http://www.hpss-collaboration.org/hpss/IDRequired.jsp.
•
Download copies of the Installation Guide and Management Guide for the appropriate version
of HPSS. It will probably be useful to print copies of these documents and keep them handy
while installing HPSS.
•
Install, configure, and verify the correct prerequisite operating system version on all HPSS,
Kerberos client and/or server, and DB2 nodes.
•
Check the format of /etc/hosts. If /etc/hosts is used to augment DNS, fully qualified
hostnames must be listed first. e.g.,
123.45.6.789 host1.domain.gov host1
•
Verify the current operating system level:
% uname -a
•
Create appropriate HPSS UNIX user accounts. The hpss user ID and hpss group ID should be
created at this time.
•
Install the prerequisite software for Kerberos, C compiler, Java, Perl, SSH, and any other
specific software that will be used by HPSS. Verify the correct patch levels are/will be
installed. Refer to Section 3.3:
Prerequisite Software Considerations on page 58 for
additional information.
