New diagnostic error messages are written to the syslog file
(/var/adm/syslog/syslog.log) when an attempt to obtain the cluster lock fails.
Internal error codes are returned to facilitate troubleshooting.
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

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. NFS
servers are hosts that “export” their local directories and make them available for client
hosts for mounting. On the NFS client, these mounted directories look like part of the
client’s local file system.
MC/ServiceGuard NFS Toolkit is a set of configuration files and control scripts which
can be customized to user-specific needs.
MC/ServiceGuard is used to create high-availability clusters of HP servers. Computer
systems with high-availability clusters allow applications to continue in spite of a
hardware or software failure. Such systems protect users from software failures as well
as from failure of a system processing unit (SPU) or local area network (LAN)
