HP Serviceguard Storage Management Suite bundles with

VxVM and VxFS

The following Serviceguard Storage Management Suite bundles all support clusters of up to 16 nodes

but differ from each other based on the Veritas Storage Foundation version they include:

 Veritas Storage Foundation Standard

 Veritas Storage Foundation for Oracle

 Veritas Storage Foundation for Oracle Enterprise

T2771xx: HP Serviceguard Storage Management

The HP Serviceguard Storage Management (SGSM) bundle integrates Serviceguard high-availability

clustering with Veritas Storage Foundation Standard, which includes full versions of Symantec’s VxVM

and VxFS. This entry-level bundle includes the following individual components:

 HP Serviceguard

 HP Serviceguard Manager

 HP Enterprise Cluster Master Toolkit

 Veritas File System

 Veritas Volume Manager

 Veritas Dynamic Multi-Pathing (DMP)

 Veritas Enterprise Administrator (VEA)

 Storage Checkpoints

 Veritas Storage Rollback

This bundle is suited for users with non-Oracle database environments who want to use the basic

Veritas Storage Foundation products in their Serviceguard cluster but do not have a need for CVM,

CFS, or any of the premium Storage Foundation components.

Users looking for features that are not available in a Serviceguard cluster with HP LVM might choose

this bundle. One important high availability feature—the DMP—that comes with this and all other

bundles is active/active path failover to storage devices that support this feature. The DMP feature of

VxVM provides path failover and load balancing. It balances I/O across all available paths between

a server and a storage array. For SG SMS versions on HP-UX 11i v2, the LVM alternate physical links

feature, PVLink, provides no load balancing and only active/passive path failover. For HP-UX 11i v3

and beyond, the I/O stack provides DMP or load balancing. DMP, along with PVlinks, provides

backwards-compatibility with current environments and additionally full load balancing.

Note

With HP-UX 11i v3, you have the option of Native Multi-Pathing in addition

to the storage

multi-pathing options mentioned earlier. For detailed

information, see “Storage Multi-Pathing choices in HP-UX Serviceguard

Environments” available at http://docs.hp.com/en/11822/storagemulti-

pathing-HPUX-SG.pdf

Note that this bundle does not include CVM or CFS. For this reason, this bundle is well suited for

failover applications but not for active/active multi-instance applications.
