PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

3.2.2 Setting Up Disk Units

Installation and Setup of Related Software

Install and set up the software products required for using shared disk units. See the installation guides and manuals of each software product.

• If the disk unit uses a Fibre Channel interface, a Fibre Channel driver for the card needs to be installed and set up. For installation details, see "Installation Procedures" in "FUJITSU PCI Fibre Channel x.x Guide for Solaris(TM) Environment."
• If the disk array unit is used with a multipath configuration, refer to the following manuals for instructions on installing and setting up the software.
  • When the GR multipath driver (GRMPD) is used
    • "GR Multipath Driver 1.0 User's Guide"
  • When the multipath disk control load balance option (MPLB) is used
    • "INSTALLATION GUIDE - Multipath Disk Control load balance option x.x for Solaris(TM) Environment"
    • "Multipath Disk Control Load Balance option x.x Guide"
  • When multipath disk control (MPHD) is used
    • "INSTALLATION GUIDE - Multipath Disk Control x.x for Solaris(TM) Environment "
    • "Multipath Disk Control x,x Guide"
• If an ETERNUS3000 or GR700 series disk array is used with a single-path configuration, you need to install and setup a hard disk driver (HDDV).
  For details on installing HDDV, see the "Hard Disk Driver x.x Guide."

Preparation for automatic shared disk configuration

Multipath disk

Before executing automatic shared disk configuration, format the logical units and assign labels to the units.

• For information on the procedures, refer to the manual ("Multipath Disk Control x,x Guide," "Multipath Disk Control load balance option," or "GR Multipath Driver 1.0 User's Guide") of the software product to be used.
• For information on automatic configuration of shared disks, see "Initial Setup of the Cluster Resource Management Facility" and "Automatic Configuration of Shared Disks."

At this stage, do not create logical paths for MPHD, MPLB, and GRMPD.

If a shared disk is automatically configured in a cluster system where MPLB or GRMPD is installed, and the disk supports the load balancing, the MPLB logical path will automatically be generated, then the resource will also be registered.

If you want to make the MPHD logical path automatically generate and the MPHD resource register by performing automatic configuration of a shared disk, it is necessary to set the parameter beforehand using the clsetacfparam(1M) command.

For details on the parameters to be set with the clsetacfparam(1M) command, see "Setting Up Shared Disk Connection Confirmation."

If the disk is not a multipath disk

Before executing automatic shared disk configuration, you need to assign a label to the disk by executing the "format(1M)" command.

For information on automatic configuration of shared disks, see "Initial Setup of the Cluster Resource Management Facility" and "Automatic Configuration of Shared Disks."
