Appendix: Using the vaildiag CLI Tool

VERITAS Array Integration Layer (VAIL) software interfaces third-party hardware storage arrays with VERITAS storage software. VAIL providers are software modules that enable VERITAS applications to discover, query, and manage third-party storage arrays.

A VAIL provider manages a specific type of third-party storage array. VAIL supports the following providers:

• vx_hicommand, which interfaces Hitachi HiCommand arrays
• vx_emc_symmetrix, which interfaces the EMC Symmetrix arrays
• vx_emc_clariion, which interfaces the EMC CLARiiON arrays
• vx_ibmshark, which interfaces the IBM ESS (Shark) arrays
• vx_netapp, which interfaces the Network Appliance (NetApp) arrays
• vx_vrts_cimvail, which interfaces CIM managed arrays
• vx_sun_t300, which interfaces the SUN T3 and T3+ arrays
• vx_hp_eva, which interfaces the HP EVA arrays
• vx_hds_9900, which interfaces Hitachi Freedom Storage Lightning 9900 Series arrays (note that these arrays can also be managed by the HiCommand provider)
• vx_hp_512, which interfaces the HP xp48 and xp512 arrays
• vx_cisco_mds, which interfaces Virtual Enclosures
• vx_cpq_ra8000, which interfaces Compaq arrays

You can use the vaildiag CLI tool to:

• Help diagnose array discovery problems
• Get configuration information for arrays that are configured for discovery by a host
• Set the path to a third-party array vendor CLI
• Rescan a storage array or VAIL provider

The vaildiag CLI tool is installed at the default location of /opt/VRTSvail/bin on all hosts where VAIL is installed, so you can run vaildiag on the host that you are querying. You can use the vaildiag CONNECT option to connect to and query a different host. For information about vaildiag, see vaildiag or the vaildiag online manual page.
