Preface

This manual, the Sun StorageTek QFS File System Configuration and Administration Guide, describes the file system software included in Sun StorageTek QFS Version 4, Update 6 (4U6).

The Sun StorageTek QFS product includes a file system that can be used as a stand-alone file system, as a shared file system, or in conjunction with the storage and archive manager contained in the Sun StorageTek SAM product. When used in conjunction with Sun StorageTek Storage Archive Manager (SAM) software, it is known as SAM-QFS.

The Sun StorageTek QFS software package runs in the following operating system (OS) environments:

Solaris 9 Operating System (OS) 04/03 or later for SPARC® platforms

Solaris 10 OS for SPARC or x64 platforms

Solaris 10 OS for x86 (32-bit) (Sun StorageTek QFS shared client only)

Red Hat Enterprise Linux 3.0 (UD-5 and UD8) for x86/x64 platforms (Sun StorageTek QFS shared client only)

Red Hat Enterprise Linux 4.0 (UD-2 and UD-4) for x64 platforms (Sun StorageTek QFS shared client only)

SuSE Linux Enterprise Server 8 (service pack 4) for x64 platforms (Sun StorageTek QFS shared client only)

SuSE Linux Enterprise Server 9 (service pack 2) for x64 platforms and SGI Altix Itanium systems (Sun StorageTek QFS shared client only)

SuSE Linux Enterprise Server 10 for x64 platforms (Sun StorageTek QFS shared client only)

Note - This is the last version of Sun StorageTek QFS that will support SuSE Enterprise Linux 8. It will not be supported in the next version of the software.

This manual is written for system administrators responsible for installing, configuring, and maintaining Sun StorageTek QFS file systems. You, the system administrator, are assumed to be knowledgeable about Solaris OS procedures, including installing, configuring, creating accounts, performing system backups, and performing other basic Solaris OS system administration tasks.
