DescriptionOption
Display device paths based on the LUN WWN.-W
Display information for the LUN with the specified WWN.-w wwn
Format options
DescriptionOption
Display information in the specified format.
nl
The supported format values are tab (default) and csv (comma-separated values).
-f format
Display information in long format, including all details
1
about the LUN.-l
Display capacity in the specified unit.
nl
The supported unit values are KB, MB (the default), and GB.
-u unit
1
Devicefile, path, target, LUN, array, host port, vendor, product, revision, controller number, and WWN
Platform-specific options
DescriptionOption
Use SCSI generic (SG) device names for Linux.
nl
-g
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.
Display persistent device special files (HP-UX 11.31 with a, w, W, and l options
only).
-P
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” (page 6).
-p
Important notes
On systems running HP-UX 11.31, HP EVAInfo might not display optimized paths. Use the
nl
scsimgr load_bal_policy command to set the load-balance policy for the LUN.
On systems running HP-UX 11.31, HP EVAInfo with [-a -l -p] or [-a -l -P] options
display the path as -l.
EVAInfo commands with invalid options can execute. You must take care when specifying
command options.
HP EVAInfo displays a maximum of 1024 paths. If your configuration contains more than
1024 paths, HP EVAInfo does not display all paths on Linux-based hosts.
On Linux hosts, HP EVAInfo sometimes displays an incorrect LUN size when additional LUNs
are presented to the host. This occurs when HP EVAInfo queries LUN properties before the
new LUNs are in a ready state. To resolve this issue, perform a rescan of SCSI devices using
the filberutils tool or hp_rescan -a, and then run HP EVAInfo.
HP recommends that you remove stale device files (physical disks in the array that have
changed or no longer exist) from the array before running HP EVAInfo.
If HP AutoPath software is installed on your system, HP EVAInfo displays a single optimized
device path.
On systems running HP-UX 11.31, the HP EVAInfo [-p] and [-P] options do not always
display persistent device file information. HP recommends that you use the ioscan m dsf
command to view this information.
