Perform SAS-specific tasks

Contributors NetAppZacharyWambold netapp-jolieg

For the SAS protocol, you determine host port addresses and make the appropriate settings.

Step 1: Determine SAS host identifiers—​Windows

Find the SAS addresses using the HBA utility, then use the HBA BIOS to make the appropriate configuration settings.

About this task

Review the guidelines for HBA utilities:

  • Most HBA vendors offer an HBA utility. Depending on your host operating system and CPU, use either the LSI-sas2flash(6G) or sas3flash(12G) utility.

  • Host I/O ports might automatically register if the host context agent is installed.

Steps
  1. Download the LSI-sas2flash(6G) or sas3flash(12G) utility from your HBA vendor’s web site.

  2. Install the utility.

  3. Use the HBA BIOS to select the appropriate settings for your configuration.

    For setting recommendations, see the Notes column of the NetApp Interoperability Matrix Tool.

Step 2: Record your configuration

You can generate and print a PDF of this page, and then use the following worksheet to record your protocol-specific storage configuration information. You need this information to perform provisioning tasks.
