Release notes in this section pertain to the RF31T, RF31T+, RF35, RF35+, RF73,
and RF74 DSSI disk devices.
B.11.1 RF73 and Other RFnn DSSI Disk Devices and Controller Memory Errors
V6.2
A problem exists with the microcode for earlier versions of RF31T, RF31T+, RF35,
RF35+, RF73, and RF74 DSSI disk devices that can cause data loss. The problem
can occur when reading data from one of these devices if the device has had a
controller memory error (also known as an error detection and correction (EDC)
error). The error could have been induced by a virtual circuit closure or faulty
hardware.
Compaq advises customers with any of these devices to check their microcode
revision levels. If the microcode revision levels are lower than the numbers
shown in Table B–1, Compaq recommends that you update the microcode. The
microcode for all models, except RF31T, RF31T+, and RF35+, is provided on the
latest OpenVMS binary distribution CD–ROM.
The RF_VERS utility, a utility program that displays the microcode revision level
of the DSSI disk devices, is also provided on the CD–ROM. Instructions both for
using the utility program and for updating the microcode are provided in this
section.
Note
If you have an RF31T, RF31T+, or RF35+ disk drive with a version of
microcode that is not supported (see Table B–1), and if you have a support
contract, contact your Compaq support representative. Otherwise, contact
your authorized reseller.
The earliest supportable revision levels of the DSSI disk microcode are shown in
Table B–1.
