5.9 OpenVMS Cluster Systems
A remedial kit will be available from the following web site to correct this
problem:
http://www.support.compaq.com/patches/
This problem exists only on Alpha platforms running OpenVMS Alpha Version
7.2x.
5.9.3 Remedial Kits Required for Extended File Cache (XFC) Used in Mixed
Version OpenVMS Cluster Systems
V7.3
The Extended File Cache (XFC), introduced in this version of the OpenVMS
Alpha operating system, improves I/O performance and gives you control over the
choice of cache and cache parameters.
If you have an OpenVMS Cluster system that contains earlier versions of
OpenVMS Alpha or OpenVMS VAX and you want to use XFC with OpenVMS
Version 7.3, you must install remedial kits on the systems that are running the
earlier versions of OpenVMS. See Section 5.9.5 for information on the required
kits.
Caution:
These remedial kits correct errors in the cache locking protocol and allow
older versions of the caches to operate safely with the new XFC. Without
the remedial kit functionality, the system or processes could hang.
5.9.4 Fibre Channel Remedial Kits Support for SANWorks DRM
V7.2-1
OpenVMS supports SANworks Data Replication Manager (DRM), except
when using the DEC-AXPVMS-VMS721_FIBRECHAN-V0300-4.PCSI kit. An
incompatibility exists between DRM and this kit that causes hard hangs. This
problem has been addressed in two new remedial kits, one for OpenVMS Alpha
Version 7.2-1 and one for OpenVMS Alpha Version 7.2-1H1. For kit names, see
Section 5.9.5.
Note that the kit name format has changed. The SCSI and Fibre Channel
remedial kits have been consolidated into one kit; the new name format reflects
this consolidation.
This remedial kit is not required for V7.3 because the relevant fix is included
with the operating system.
5.9.5 Remedial Kits Needed for Cluster Compatibility
V7.3
Before you introduce an OpenVMS Version 7.3 system into an existing OpenVMS
Cluster system, you must apply certain remedial kits to your systems running
earlier versions of OpenVMS. If you are using Fibre Channel, XFC or Volume
Shadowing, additional remedial kits are required. Note that these kits are
version-specific.
Table 5–1 indicates the facilities that require remedial kits and the file names of
the remedial kit files.
