3par Autonomic Groups
HP 3PAR Autonomic Groups is a feature designed to simplify storage provisioning for clustered and virtual
server environments. Use of Autonomic Groups reduces opportunities for human error by reducing manual
repetition of tedious commands, making the provisioning process more reliable.
About 3PAR Autonomic Groups
The 3PAR InForm Operating System provides a simple, two-step process for the common task of
provisioning VVs and exporting them to application servers as VLUNs. While much simpler than provisioning
with traditional storage arrays, when multiplied by the numerous hosts which are characteristic of
virtualized utility computing environments, the repetition of even the simplest provisioning tasks can
consume significant resources and leave room for human error.
3PAR Autonomic Groups takes autonomic storage management a step further by allowing both hosts and
VVs to be combined into “groups” or “sets” which can then be managed as a single object. Adding an object
to an autonomic group applies all previously performed provisioning actions to the new member. For
example, when a new host is added to a group, all volumes are autonomically exported to that group with
absolutely no administrative intervention (hostset).
In the same way, when a new volume is added to a group, that volume is also autonomically exported to all
hosts in the group—intelligently and without requiring administrator action (vvset).
Host Groups
Hosts can be grouped into autonomic groups that can be managed as one host. If you have a group of hosts
that require the same administrative procedures, it is easier to group those hosts into an autonomic group
and manage them together.
Virtual Volumes (VVs) can be exported to multiple Hosts.
As a member of an exported VV Autonomic Group
As VV exports to each individual Host
Removing the Group does not affect any exports to individual Hosts.
Status is visible in showvlun etc with ‘set:’ prefix in the hostname for the template and ‘host set’ as
the export type. The active export shows the individual host with a ‘host set’ export type.
Virtual Volumes
VVsets are a mechanism for grouping virtual volumes logically so that a common action can be applied to all
virtual volumes simultaneously. Creating a virtual volume autonomic group VVs can also be combined into
autonomic groups, or sets, that can be managed as a simple object. Creating a vvset is much like creating a
hostset.
Creating an autonomic host group
Hosts can be combined into autonomic groups, which are sets that can be managed as a single object. To
create an autonomic host group, one must specify a name for the host set and the hosts to be included in
that set.

Select Hosts Expand selection Select Host Sets Right Click
2.
New Assistant window with hostset properties with required steps to create new host set. Type
Name that includes with Prefix HS_CLU which indicates is a hostset cluster Preceded with
Operating System (VMWARE, WIN or LINUX) and Application name based on standard naming
conventions).
Note: It is recommendable to include in Comments full description to easily identify characteristics
of hosts associated (e.g. VMWare ESXi Production SQL Cluster).
3.
Select hosts that will belong to new hostset, for each member type arrown pointing down to
Assigned frame, host selected will be included in that section.
4. Repeat operation listed above for each host member that needs to be included in hostset
5.
Carefully review summary window with host selected before create new hostset. And type Finish
to complete host set creation.
createhostset
The createhostset command defines a new set of Hosts and provide the option of assigning one or more
extisting Hosts to that set. The command also allows the addition of Hosts to an existing set by use of the ‘add’.
createhostset [options] <setname> [<host | pattern>…>
Options:
-add
-comment
-domain
List of Hosts to be added to an existing set
Specify a comment related to the set
Create the host set in the specified domain.
A host set must be in the same domain as its members.
Any hosts added to the host set automatically see all VLUNs available to the host set, provided there are no
conflicting LUN IDs. If the added host has an exported LUN ID in the LUN ID range of the host set, the host
cannot see the LUN and must be assigned a new ID.
showhostset
Show all Host sets defined to the system. Including wildcard * will show host sets containing matching
pattern
Exporting a Virtual Volume to a host group
A VV is made available to a host, or exported, by creating a virtual LUN (VLUN). Autonomic groups may be
used for both VVs and hosts, allowing a VV or set of VVs to be exported to a set of hosts with a single
operation. The steps for exporting the VV or VV set created previously to the host set created in a previous
example using the HP 3PAR Management Console.
