SAS-2 and SAS-3 Configuration Issues

The SAS driver for Solaris 10 (Update 8 and later) and Solaris 11 (11.1 and later) disrupts communications between Oracle Solaris and common tape backup applications.

The SAS driver only allows one device driver to attach per device (sg, sgen, st, and so forth). Users must have every component in the following list to be affected:

  • Oracle Solaris 10 (Update 8 or later) or Solaris 11 (11.1 and later)
  • Any SAS-2 or SAS-3 HBA
  • Tape drives or libraries using a SAS-2 or SAS-3 connection
  • A backup application that requires multiple SAS drivers. The most common backup applications that use multiple device drivers include:
    • CA ARCserve
    • HP Data Protector
    • IBM Tivoli Storage Manager

A SAS tape drive attached through a SAS-2 or SAS-3 HBA will work on the Solaris system using just the Solaris native commands such as dd or tar. However, this configuration is recommended for a stand-alone drive only.

If you want to use Oracle Solaris 10 (Update 8 and later) or Solaris 11 (11.1 and later) and a SAS-2 or SAS-3 HBA, you should use one of the following backup applications:

  • Oracle Secure Backup (OSB): 10.4.0.2 or later
  • EMC Networker: current release level with all patches applied
  • Symantec NetBackup: current release level with all patches applied
