Solaris SAN Configuration and Multipathing Guide

Chapter 5 Configuring SAN Devices

This chapter provides the high level overview of the steps used to configure SAN devices. In the Solaris 10 OS, FCAL, fabric, and point-to-point connected devices are made available to the host automatically. This feature differs from previous versions of the SAN Foundation software running on the Solaris 8 or the Solaris 9 OS. In those versions, manual configuration steps were required to achieve fabric-connected device availability on the host. To find out how to manually configure fabric-connected devices, refer to Appendix A, Manual Configuration for Fabric-Connected Devices.

The following topics are discussed:

SAN Device Considerations

Be aware of the following considerations before configuring the Sun StorageTek Traffic Manager software.

Adding SAN Devices

Adding and removing SAN devices requires knowledge of the following commands:

The cfgadm and cfgadm_fp commands are used most frequently to configure storage devices on a SAN. Refer to the appropriate man page for detailed instructions about how to use each command.

ProcedureTo Add a SAN Device

  1. Create the LUNs desired on the SAN device.

  2. If necessary, apply LUN masking for HBA control on the SAN device.

  3. Connect the storage device to the system.

  4. If necessary, create port-based or WWN zones on the switch on the SAN device.

  5. Run the fsck or newfs commands on the device, if used for file systems.

  6. Mount any existing file systems available on the storage device’s LUNs or disk groups.

    Note –

    You might need to run the fsck command to repair any errors in the LUNs listed in the /etc/vfstab file.

Configuring Fabric Boot Devices on SPARC

The Sun StorageTek Traffic Manager software allows a Solaris 10 OS SPARC server to be booted from a fabric disk device.

Boot Considerations

Fabric boot devices can be added through the Solaris 10 OS interactive installation GUI or text installer just as internal boot devices have been added in the previous Solaris OS releases. Refer to the Solaris 10 OS installation guide for details. You should consider the following points while enabling a fabric boot device.
