HP-UX 11i September 2002 Release Notes

HP-UX 11i Version 1.0 Operating Environment Applications
HP-UX 11i Mission Critical Operating Environment (MCOE)
Chapter 6
118
MC/ServiceGuard supports the online replacement of network and I/O interface cards,
which is allowed by the HP-UX 11i Operating Environments.
Impact
Disk space required for MC/ServiceGuard is 47MB. The memory required is 6MB, plus
70KB per package in the cluster, plus 300KB per Event Monitoring Service (EMS)
resource in the cluster. This total amount is required on all cluster nodes, regardless of
whether a given package or resource is on that node or not.
The EMS-CORE file set is no longer included as part of the MC/ServiceGuard product,
even though EMS (B7609BA) is still a dependency and must be installed with
MC/ServiceGuard.
NOTE MC/ServiceGuard does not provide Native Language Support. However, separate native
language versions of documentation are available as a part of product B3935DA and
B3936EA with the following options:
• AB0 - Traditional Chinese
• AB1 - Korean
• AB2 - Simplified Chinese
• ABA - English
• ABJ - Japanese
Documentation
• MC/ServiceGuard Version A.11.14 Release Notes Second Edition (B3935-90055)
• Managing MC/ServiceGuard, Ninth Edition (B3936-90065)
These documents are available on the HP-UX 11i Instant Information CD and on the
Web at http://docs.hp.com/hpux/ha/.
MC/ServiceGuard NFS Toolkit
Multi-Computer/ServiceGuard Network File Server (MC/ServiceGuard NFS) Toolkit
version A.11.11 uses MC/ServiceGuard to set up highly available NFS servers. An NFS
server is a host that “exports” its local directories (makes them available for client hosts
to mount using NFS). On the NFS client, these mounted directories look to users like
part of the client’s local file system. With MC/ServiceGuard NFS, the NFS server
package containing the exported file systems can move to a different node in the cluster
in the event of failure.
updated for
December 2001
• MC/ServiceGuard NFS Toolkit versions A.11.00.05 and A.11.11.02 are major
releases. Both of these versions have dependencies on MC/SG A.11.13 that provide
the integrated solution for multiple MC/ServiceGuard partner software working
together under the new MC/SG framework. MC/SG NFS Toolkit has been
re-architected to fit under the new framework.
• NFS-related control functions and variables have been extracted from
MC/ServiceGuard package control script to a separate NFS specific control script,
hanfs.sh. When the MC/ServiceGuard package is started, it will check for this
script under the package directory, and if it exists, will invoke NFS control script.
