HP 3PAR Upgrade Pre-Planning Guide

6
Host persona 6 will not be supported for any version of VMware ESX/ESXi with future HP 3PAR OS versions after HP
3PAR OS 3.1.3 MU1 and its MUs. HP recommends that customers migrate their VMware ESX configurations on HP
3PAR to Host Persona 11 with HP 3PAR OS 3.1.2 or later.
7
VMware ESX 3.5 is not supported in HP 3PAR OS 3.1.1 or later.
8
As of VMware ESX 4.0, a change of the SATP rules on hosts to enable active/active round robin by default is
recommended. See the HP 3PAR VMware ESX Implementation Guide for instructions about changing the VMware
ESX/ESXi SATP rules. To obtain this document, see the HP Storage Information Library:
www.hp.com/go/storage/docs
9
HP recommends host persona 11 for all supported VMware ESX versions with HP 3PAR OS 3.1.2 and later. Changing
the persona from 6 to 11 for existing Persona 6 hosts is an offline process.
10
Enabling host persona 2 will enable A/A multipath on LUNs by default. This change will require a restart. Do not change
the host persona unless you can restart the Windows Server 2008. If you do not restart the server, the host will lose the
mapping of the LUNs.
11
From HP 3PAR OS 3.1.3 MU1, HP requires host persona 15 for Windows Server2012 R2, Windows Server 2012, and
Windows Server 2008 R2 and non-R2 hosts. However, host persona 2 is automatically assigned following an online
HP 3PAR OS upgrade from OS version 3.1.2. After such an upgrade, you must change host persona 2 to host persona
15. Before changing host personas, see “Windows Server OS Guidelines” (page 25) for instructions to prevent loss of
LUN mapping.
12
Microsoft enables A/A multipathing by default at Windows Server 2008 R2.
13
For Windows Server 2008 R2, configurations of persona 6 and 1 need to be changed manually to persona 2 after an
upgrade to HP 3PAR OS 3.1.2. The Windows Server host needs to be shut down when the persona change is performed
and then brought back online in order to properly configure the ALUA paths support in persona 2.
• To change the host persona of a host:
cli% sethost –persona <persona _number> <host_name>
• List of host persona's available on an HP 3PAR OS release:
cli% showhost -listpersona
• To verify the host persona setting of a host:
cli% showhost persona <host_name>
NOTE: Hosts that are offline or powered down during an upgrade from HP 3PAR OS 2.2.4 to
HP 3PAR OS 2.3.1 are assigned host persona 6 by the upgrade operation. This default persona
6 assignment would prevent HP-UX, AIX, and NetApp hosts from operating correctly. Therefore,
explicit action is required by the user to set the persona for such hosts according to the persona
guidance in Table 5 (page 12).
HP 3PAR StoreServ Storage Configuration Guidelines
The following guidelines must be observed when planning an online HP 3PAR OS upgrade.
• The HP 3PAR StoreServ Storage must be in a “healthy” state (with no failed or degraded
physical disks, cages, FCALs, nodes, etc.). The HP 3PAR OS upgrade software performs an
automated check and, if the system is not in a healthy condition, causes the upgrade to fail.
• A VLUN for each exported volume must be exported to a defined host on at least two fully
operational paths that span adjacent storage server nodes, an even-numbered node followed
