HP 3PAR RedHat and Oracle Linux Implementation Guide

If the virtual volumes in use report a 16-byte WWN, the ASL extracts an AVID number of 0 for all
VVs, and Symantec sequentially enumerates the DMP devices to generate a unique DMP disk
name. In this case, the resulting disk names would be:
3pardata4_0
3pardata4_0_1
3pardata4_0_2
The name scheme used does not impact DMP functionality. However, if you want the DMP name
to contain the VV AVID number, Symantec provides updated ASLs that will properly extract the
AVID number. If AVID naming is desired, use the following ASL versions:
Storage Foundation 5.1 (all) 3PAR ASL version 5.1.134.100 or later
Storage Foundation 6.0 to 6.0.4 ASL version 6.0.400.100 or above
To obtain the Veritas ASL for the HP 3PAR StoreServ Storage, complete the following tasks:
1. Download the latest Veritas ASL for the HP 3PAR StoreServ Storage System from the following
website:
Symantec
Select 3PAR as the vendor. For ASLs for SFHA versions earlier than 5.0, see this technical
note:
Symantec TECH61169
NOTE: Specific models of HP 3PAR StoreServ Storage arrays may not be listed on the
website, but the ASL works on all models of HP 3PAR StoreServ Storage arrays.
2. To install the ASL, the Veritas vxconfigd daemon must be running. Running vxinstall
will start the daemon. Once you install the ASL package, you must run the vxdctl enable
command to claim the disk array as an HP 3PAR StoreServ Storage array.
3. Configure the Veritas vxdmp driver to manage the HP 3PAR StoreServ Storage paths providing
path failure management and dynamic load balancing.
