7.3 Cross-Platform Issues for NSS Features

The following features of NSS are available for NSS on NetWare but are not supported for NSS on Linux.

7.3.1 Multipath I/O to Devices

If a device has multiple connection paths between the hardware controller and the HBA on the server, each path appears as a separate device to the operating system. You must use multipath management tools to resolve the apparent devices into a single multipath device.

Media Manager provides multipath I/O for devices on NetWare. Media Manager is not available on Linux. For information, see Section 14.0, Managing Multipath I/O to Devices (NetWare).

On Linux, use Linux multipath I/O management tools. You should configure multipath I/O before using NSS management tools to create NSS software RAIDs, pools, or volumes on the devices. For information, see Section 15.0, Managing Multipath I/O to Devices (Linux).

7.3.2 NSS Support for Removable Media

Removable media such as CDs, DVDs, CD and DVD image files, and DOS partitions are typically mounted as file systems native to the Linux or NetWare platform on the server.

On NetWare, CDs, DVDs, CD and DVD image files, and DOS partitions are mounted as NSS volumes. Disks in USB drives are mounted as local DOS FAT partitions. For information, see Section 21.0, Managing Removable Media (NetWare).

On Linux, removable media and partitions are mounted by using Linux POSIX file systems options. For information, see File Systems in Linux in the SUSE Linux Enterprise Server 10 SP3 Installation and Administration Guide.

7.3.3 NSS Support for Transaction Tracking

NSS provides file transaction tracking with the Transaction Tracking System™ (TTS™) for NSS volumes on NetWare. TTS is not available for NSS on Linux. For information about using TTS, see Section 23.2, Using the Transaction Tracking System for Application-Based Transaction Rollback (NetWare).
