HP Serviceguard Storage Management Suite (SG SMS) bundles provide several options

for clustering and storage. The information in this document applies to the SG SMS

bundles that include the Veritas Storage Foundation™ 5.0 Cluster File System and

Cluster Volume Manager by Symantec:

• SG SMS version A.02.00 bundles T2775CA, T2776CA, and T2777CA for HP-UX 11i

• SG SMS version A.02.00 Mission Critical Operating Environment (MCOE) bundles

T2795CA, T2796CA, and T2797CA for HP-UX 11i v2

• SG SMS version A.02.00 bundles T2775CB, T2776CB, and T2777CB for HP-UX 11i

• SG SMS version A.02.00 High Availability Operating Environment (HAOE) bundles

T8685CB, T8686CB, and T8687CB for HP-UX 11i v3

• SG SMS version A.02.00 Data Center Operating Environment (DCOE) bundles

T8695CB, T8696CB, and T8697CB for HP-UX 11i v3

SG SMS bundles that include the Veritas Storage Foundation Cluster File System (CFS)

allow clustered servers running HP-UX 11i to mount and use the same file system

simultaneously, as if all applications using the file system are running on the same

server. SG SMS bundles that include CFS also include the Veritas Storage Foundation

Cluster Volume Manager (CVM). CVM makes logical volumes and raw device

applications accessible throughout a cluster.

As SG SMS components, CFS and CVM are integrated with HP Serviceguard to

form a highly available clustered computing environment. SG SMS bundles

that include CFS and CVM do not include the Veritas™ Cluster Server by

Symantec (VCS). VCS functions that are required in an SG SMS environment

are performed by Serviceguard. This document focuses on CFS and CVM

administration in an SG SMS environment.
