Before Configuring ACSLS for the SL3000

Before you configure ACSLS for the SL3000:

  • Connect the SL3000 to ACSLS

  • Verify that all of the components of the SL3000 are operational.

    ACSLS builds its library configuration from the information reported by the library. If SL3000 components are not operational, the library information may not be reported to ACSLS, and the ACSLS configuration of the SL3000 could be incomplete.

Connecting the SL3000 to ACSLS

The SL3000 library uses TCP/IP protocol over an Ethernet physical interface to manage and communicate with the host and ACSLS. This interface enables ACSLS to connect to, and communicate with the SL3000.

Using TCP/IP connection(s) to the SL3000 provide these advantages:

  • ACSLS can send multiple concurrent requests to the library, and the library can process them in parallel. This improves library performance.

  • When connected using TCP/IP, the SL3000 supports Dual TCP/IP and Redundant Electronics.

  • The TCP/IP Host/Library Interface is a richer interface than the SCSI Media Changer over Fibre Channel. More information is available to ACSLS about library status, errors, and so forth.

It is preferable to have the SL3000 library on a separate subnet, or a controlled network to protect it from floods of ARP broadcasts.

Verifying that all SL3000 Components are Operational

To verify that all of the components of the SL3000 are operational, logon to the StorageTek Library Console (SL Console).

Refer to the SL3000 User's Guide for procedures.

Configuring SL3000 to ACSLS

Once the SL3000 components are operational, configure SL3000 to ACSLS. You can use either acsss_config (see Setting CSI Tuning Variables) or Dynamic Configuration (see Using the Dynamic Configuration (config) utility).

Auditing the SL3000

Audit an SL3000 after it is configured or reconfigured to ACSLS. Auditing informs ACSLS which cells are part of the partition that it is managing in this library and displaying the cells that are actually present on panel drives or CAPs.

  • First, configure or reconfigure an SL3000 to ACSLS.

  • Audit the ACS.

  • Look at the allocated and free cells by entering any of the following commands:

    • free_cells.sh -a

    • get_license_info

    • display cell * -f status

  • Look at the drives using either:

    • query drive all

    • display drive * -f type serial_num wwn
