Description

EVAInfo is a command line utility developed for the HP StorageWorks Enterprise Virtual Array (EVA). It maps device special files to LUNs presented from the EVAs to the server or host and the associated port and array controller on the EVA. This document is specific to EVAInfo 9.0. NOTE: Starting with version 8.0, EVAInfo is distributed on the HP StorageWorks Storage System Scripting Utility (SSSU) CD. Update recommendation Routine

Synopsis

The evainfo [options] [raw_device_file] command identifies the logical unit numbers (LUNs) presented to a host from an HP EVA, and displays information about the connected port and controller. The command output also indicates if the device path is active and optimized for I/O for the LUN. The active and optimized path information is supported for HP StorageWorks 3000/5000 Enterprise Virtual Array (EVA3000/5000) with Active/Active firmware, and HP StorageWorks 4x00/6x00/8x00 and 4400 Enterprise Virtual Array storage systems. The command is run as root or as a user with root privileges. IMPORTANT: The command output is displayed in horizontal format, one LUN per line, and therefore is best viewed in a window with a width of at least 80 columns. HP recommends that you use a window with a width of at least 132 columns. However, the optional long format output contains more details and is optimally viewed in an even wider window.

Product models

EVAInfo is supported on: · EVA4x00/6x00/8x00 · EVA3000/5000 with Active/Active firmware · EVA3000/5000 with Active/Passive firmware, with the restriction that controller information is not displayed in the output · EVA4400

Operating systems

EVAInfo is supported on the following operating systems: · HP-UX PA-RISC 11.11/11iv1 (64b) · HP-UX 11.23 PI/11iv2 (64b PA-RISC, 64b Intel) · HP-UX 11.31/11iv3 (64b PA-RISC, 64b Intel) · Red Hat Enterprise Linux AS & ES 4.0 Update 6, 7 (x86 32-bit, x64 64-bit, Itanium) · Red Hat Enterprise Linux AS & ES 5.0 Update 1, 2 (x86 32-bit, x64 64-bit, Itanium) · SUSE Linux Enterprise Server 9.0 SP3 (x86, x86_64 32-bit, x64 64-bit, Itanium) · SUSE Linux Enterprise Server 10.0 SP1, SP2 (x86, x86_64 32-bit, x64 64-bit, Itanium)

Installation instructions

Install EVAInfo from the HP StorageWorks System Scripting Utility (SSSU) CD that came with your HP Command View EVA media kit. 1. Download EVAInfo to a directory on the server or host. 2. Ensure that the binary file has execute permission. You can use the chmod command to set the execute permission. For example, # chmod 555 evainfo or # chmod u+x evainfo. 3. Execute the binary as root. For a list of supported options, enter # ./evainfo -h.

Options

This section describes the options available for the evainfo [options] [raw_device_file] command. Basic options:

-a Display information on all EVA LUNs presented to the host. Display information on the specified EVA LUN: For HP-UX 11.11 and 11.23, the raw device is in the format /dev/rdsk/cXtYdZ (for example, /dev/rdsk/ c23t0d1. For Linux, the raw_device is in the format /dev/sdX or /dev/sgY (for example, /dev/sdi or /dev/sg12).

nl

-d raw_device

-h -v -W -w wwn

Display help on options. Display version details. When specified with other options, only the version information appears. Display device paths based on the LUN WWN. Display information for the EVA LUN with the specified WWN.

4

Format options:

-f format -l -u unit Display information in the specified format. The supported format values are tab (default) and csv (comma-separated values). Display information in long format, including all details1 about the LUN. Display capacity in the specified unit. The supported unit values are KB, MB (default) or GB.

1

Devicefile, path, target, LUN, array, host port, vendor, product, revision, controller number, and WWN.

Platform specific option:

Use SCSI generic (sg) device names for Linux. This option also enables inclusion of controller devices in the output. The output for controller devices shows the array WWN, but not capacity information. For HP-UX, specifying the -g option has no effect on processing or output. -P Display persistent device special files (HP-UX 11.31 with ­a, ­w, ­W, and ­l options only). Display agile device special files and their persistent device special files (HP-UX 11.31 with ­a, ­w, ­W, and ­l options only). See Sample Output.

-g

-p

Important notes

On systems running HP-UX 11.31, EVAInfo might not display optimized paths. Use scsimgr load_bal_policy to set the load balance policy for the LUN. On systems running HP-UX 11.31, EVAInfo with [-a -l -p] or [-a -l -P] options display the path as -1. EVAInfo displays the size of a large LUN as 0 MB. To view the size of a large LUN, use HP SSSU. Intermittently on Linux hosts, EVAInfo displays an incorrect size of a LUN when additional LUNs are presented to the host . This happens if EVAInfo queries LUN properties before the new LUNs are in a ready state. To resolve this issue, run rescan of SCSI devices using HP_Rescan or the filberutils tool, and then run EVAInfo. HP recommends that you remove stale device files from the system before running EVAInfo. Autopath, if installed on your system, can cause EVAInfo to not display all possible device paths.
