Chapter 1. HPSS 7.1 Configuration Overview

1.1. Introduction

This chapter defines the high-level steps necessary to configure, start, and verify correct operation of a

new 7.1 HPSS system, whether that system is created from scratch or created by conversion from a 6.2

HPSS system.

To create or modify the HPSS configuration, we recommend that the administrator first be familiar with

the information described in the HPSS Installation Guide, Chapter 2: HPSS Basics and Chapter 3: HPSS

Planning.

Before performing the procedures described in this chapter, be certain that the appropriate system

preparation steps have been performed. See the HPSS Installation Guide, Chapter 4: System Preparation

for more information. For a system created from scratch, be certain that the HPSS installation and

infrastructure configuration have been completed. See the HPSS Installation Guide, Chapter 5: HPSS

Installation and Infrastructure Configuration for more information. To convert from a 6.2 system, see

the HPSS Conversion Guide for HPSS release 7.1.

1.2. Starting the SSM GUI for the First Time

The HPSS system is ready to be configured using SSM once the HPSS software is installed on the node

and the HPSS infrastructure components are configured. In order to start the SSM GUI you must first

start all infrastructure components and the SSM System Manager as follows:

% /opt/hpss/bin/rc.hpss -m start

Next you will need to add an SSM Admin user. To do this you will need to invoke the hpssuser utility as

follows:

% /opt/hpss/bin/hpssuser -add hpss -<unix|krb> -ssm

The above commands must be done as root!

Once the SSM Admin user has been created, you can invoke the SSM GUI as follows (for hpssgui.pl

options, see the hpssgui man page):

% /opt/hpss/bin/hpssgui.pl

Note: This command may be done as an HPSS user.

When the SSM GUI is running you can begin to configure the rest of HPSS (servers, devices, etc) as

described in the following sections. For more information on SSM, see Chapter 3: Using SSM on page

31.

1.3. HPSS Configuration Roadmap (New HPSS Sites)

The following steps summarize the configuration of an HPSS system when creating the 7.1system from

scratch (not upgrading from a previous release). It is important that the steps be performed in the order

HPSS Management Guide November 2009

Release 7.3 (Revision 1.0) 15

listed. Each step is required unless otherwise indicated. Each step is discussed in more detail in the

referenced section.

1. Configure storage subsystems (Section 4.2.2: Creating a New Storage Subsystem on page 76)

Subsystems can be configured only partially at this time. The Gatekeeper, Default COS, and

Allowed COS fields will be updated in a later step.

2. Configure HPSS storage policies

· Accounting Policy (Section 13.2.1: on page 330)

· Log Policies (Section 9.2: Log Policies on page 295)

· Location Policy (Section 2.4: Location Policy on page 26)

· Migration Policies (Section 6.4: Migration Policies on page 180)

· Purge Policies (Section 6.5: Purge Policies on page 189)

3. Configure HPSS storage characteristics

· Storage Classes (Section 6.1.1: Configured Storage Classes on page 157)

· Storage Hierarchies (Section 6.2: Storage Hierarchies on page 170)

· Classes of Service (Section 6.3: Classes of Service on page 174)

4. Configure HPSS servers (Section 5.1: Server Configuration on page 87)

5. Create global configuration (Section 4.1: Global Configuration Window on page 72)

6. Configure MVR devices and PVL drives (Section 7.1: Configure a New Device & Drive on page

196)

7. Configure file families, if used (Section 6.6: File Families on page 193)

8. Update storage subsystem configurations with Gatekeeper and COS information (Section 4.2.4:

Modifying a Storage Subsystem on page 81 and Section 4.2.3:Storage Subsystem Configuration

Window on page 76)

9. Create the endpoint map (Section 5.1.3: Location Server Additional Configuration on page 99).

1.4. Initial HPSS Startup Roadmap (All Sites)

This section provides instructions for starting the HPSS servers and performing post-startup

configuration. For sites which are converting from 6.2, only step 1 may be necessary. For sites

configuring a new 7.1 system from scratch, all steps are necessary:

1. Start the HPSS servers (Section 5.2.2: Starting HPSS Servers on page 149)

2. Unlock the PVL drives (Section 7.4.2: Locking a Drive on page 220)

3. Create HPSS storage space:

A. Import volumes into HPSS (Section 8.1.1: Importing Volumes into HPSS on page 223)

HPSS Management Guide November 2009

Release 7.3 (Revision 1.0) 16

B. Create storage resources (Section 8.1.2: Creating Storage Resources on page 234)

4. Create additional HPSS Users (Section 13.1.1: Adding HPSS Users on page 325)

5. Create Filesets and Junctions (Section 10.1: Filesets & Junctions List on page 308 and Section

10.5: Creating a Junction on page 315)

6. Create HPSS /log Directory

If log archiving is enabled, using an HPSS namespace tool such as scrub or ftp, create the /log

directory in HPSS. This directory must be owned by hpsslog and have permissions rwxr-xr-x.

The /log directory can be created by the root user using ftp as follows:

% ftp <node> <HPSS Port> # login as root user

ftp> mkdir /log

ftp> quote site chown hpsslog /log

ftp> quote site chmod 755 /log

1.5. Additional Configuration Roadmap (All Sites)

This section provides a high level roadmap for additional HPSS configuration.

1. Configure HPSS User Interfaces (Chapter 14: User Interfaces on page 339)

2. Set up Backup for DB2 and Other Infrastructure (Chapter 15: Backup and Recovery on page 356)

3. Set up High Availability, if desired (HPSS Installation Guide, Chapter 3: HPSS Planning)

4. Optionally configure support for both authentication mechanisms (HPSS Installation Guide,

Section 5.9: Supporting Both Unix and Kerberos Authentication for SSM)

1.6. Verification Checklists (All Sites)

This section provides a number of checklists regarding configuration, operational and performance

issues.

1.6.1. Configuration Checklists

After HPSS is running, the administrator should use the following checklists to verify that HPSS was

configured or converted correctly:

Global Configuration

• Verify that a Default Class of Service has been selected.

• Verify that a Root Core Server has been selected.

Storage Subsystem Configuration

• Verify that a Default Class of Service has been selected if desired.

• Verify that a Gatekeeper has been selected if gatekeeping or account validation is required.

• Verify that the COS Name list has been filled in correctly.

HPSS Management Guide November 2009

Release 7.3 (Revision 1.0) 17

• Verify that a Core Server and Migration Purge Server have been configured for each storage

subsystem.

• Verify that each storage subsystem is accessible by using lsjunctions and ensuring that there is at

least one junction to the Root fileset of each subsystem. (The root fileset for a given subsystem

can be found in the specific configuration for the subsystem’s Core Server)

Servers

• Verify that all required HPSS servers are configured and running.

• Verify that all servers are configured with the intended level of logging, whether using their

server specific policies or the default policy. Also, verify that all Core Server and Mover log

policies have the DEBUG flag turned on to aid in the diagnostics of any future problems.

Devices and Drives

• Verify that all devices/drives are configured and each is assigned to an appropriate PVR/Mover.

• For tape devices, verify that the “Locate Support” option is enabled if supported.

• For tape devices, verify that the “NO-DELAY” option is enabled if supported by the device.

• For disk devices, verify that the “Bytes on Device” and “Starting Offset” values are correct.

• Verify that all configured drives are unlocked.

Storage Classes

• Verify that all storage classes are defined and each has sufficient free storage space.

• Verify that each storage class that will be migrated and purged is configured with the appropriate

migration and purge policy.

• Verify that no storage class at the lowest level in a hierarchy is configured with a migration or

purge policy.

• To support repack and recover of tape volumes, verify that the stripe width of each tape storage

class is less than half of the number of available drives of the appropriate drive type.

Storage Hierarchies

• Verify that all storage hierarchies are defined.

Classes of Service (COS)

• Verify that all classes of service are defined.

• Verify that each COS is associated with the appropriate storage hierarchy.

• Verify that the COS is configured to use the characteristics of the hierarchy and the underlying

storage classes. In addition, verify that the classes of service have the correct Minimum File Size

and Maximum File Size values. If these sizes overlap, the file placement may be indeterminate

when the user creates a file using the size hints. For classes of services which are not to be used as

part of standard file placement, set their Force Selection flag to ON so that they will only be

HPSS Management Guide November 2009

Release 7.3 (Revision 1.0) 18

chosen if specified by their COS ID.

• Verify that classes of service with multiple copies have the Retry Stage Failures from

Secondary Copy flag enabled.

File Families, Filesets, and Junctions

• Verify that file families and filesets are created according to the site’s requirements.

• Verify that each fileset is associated with the appropriate file family and/or COS.

• Verify that each fileset has an associated junction.

User Interfaces

• Verify that the desired HPSS user interfaces (FTP, PFTP, Client API, etc.) are configured

(Chapter 14 : User Interfaces on page 339).

1.6.2. Operational Checklists

The administrator should follow these checklists to ensure that HPSS is operating properly.

Configured user interfaces

• Create files of various sizes on each defined COS.

• Verify that the files are created in the expected storage class with acceptable transfer rates.

• If necessary, redefine the associated storage class definition to enhance the throughput

performance.

• The characteristics fields (Transfer Rate, Latency, etc.) in the storage class and class of service

definition should be updated to reflect actual performance results.

• After the files are created on the correct storage class, verify that the files are created with correct

file ownerships and permissions.

• Verify that other file operations (delete, chmod, copy, etc.) work.

• If accounting is configured, verify that the files are created with the correct accounting indices.

• If file families, filesets and junctions are configured, verify that they work as intended.

Devices and Drives

• Ensure that each drive mounts, reads, and writes.

Storage Management

• Verify that migration and purge operations work as intended.

• Start Migration and Purge operations manually to verify that files are migrated and purged

correctly.

• Verify that files can be accessed after being migrated/purged.

HPSS Management Guide November 2009

Release 7.3 (Revision 1.0) 19

• Monitor free space from the top level storage class in each hierarchy to verify that the migration

and purge policy are maintaining adequate free space.

1.6.3. Performance Checklist

Measure data transfer rates in each COS for:

• Client writes to disk

• Migration from disk to tape

• Staging from tape to disk

• Client reads from disk

Transfer rates should be close to the speed of the underlying hardware. The actual hardware speeds can

be obtained from their specifications and by testing directly from the operating system (e.g., using dd to

read and write to each device). Keep in mind that transfer performance can be limited by factors external

to HPSS. For example, HPSS file read performance may be limited by the performance of the UNIX file

system writing the file rather than limits inside HPSS.
