System Requirements - Hitachi TAGMASTORE MK-90RD011-25 User Manual

3.1

System Requirements

CCI operations involve the CCI software on the UNIX/PC server host and the RAID storage
system(s) containing the command device(s) and the Hitachi TrueCopy and/or ShadowImage
pair volumes. The system requirements for CCI are:
CCI software product. The CCI software is supplied on CD-ROM or diskette. The CCI
software files take up 2.5 MB of space. The log files can take up to 3 MB of space.
Host platform. CCI is supported on the following host platforms.
See Table 3.1 – Table 3.8 for detailed information on supported OS versions.
Solaris, Solaris/x86, HP-UX, AIX, Linux, Linux/IA64, DYNIX/ptx
OpenVMS/IA, VMware, Windows 2008, Windows 2003, Windows 2000, Windows NT,
Windows CE .NET
Note: TrueCopy Asynchronous platform and storage system support may vary. Please
contact your Hitachi Data Systems team for the latest information on Hitachi RAID
storage system support for CCI.
Root/administrator access to the host is required to perform CCI operations.
–
Static memory capacity: minimum = 300 KB, maximum = 500 KB
–
Dynamic memory capacity (set in HORCM_CONF): maximum = 500 KB per unit ID
CCI supports several failover products, including FirstWatch, MC/ServiceGuard,
–
HACMP, TruCluster, and ptx/CLUSTERS. Please contact your Hitachi Data Systems
account team for the latest information on failover software support for CCI.
The system which runs and operates Hitachi TrueCopy in an HA configuration must
–
be a duplex system having a hot standby configuration or mutual hot standby
(mutual takeover) configuration. The remote copy system must be designed for
remote backup among servers and configured so that servers cannot share the
primary and secondary volumes at the same time. The information in this document
does not apply to fault-tolerant system configurations such as Oracle Parallel Server
(OPS) in which nodes execute parallel accesses. However, two or more nodes can
share the primary volumes of the shared OPS database, and must use the secondary
volumes as backup volumes.
Host servers which are combined when paired logical volumes are defined should run
–
on the operating system of the same architecture. If not, one host may not be able
to recognize a paired volume of another host, even though HORCM can run properly.
