Mark5 Version 2.2.1 Release Notes
New Features:
•
Official release of Mark5A application to support SDK9.2
•
This is the first official release of the Mark5A/5B/5B+ code that unifies the antenna's and
correlator DIM code for Mark5A (Mark5B/5B+ is still a separate package for the DOM
mode at the correlators) and allows support for disk modules > 8TB.
•
The Mark5 code can be used on the correlator for Mark5A's
•
This version of code links the Mark5 application to Conduants' SDK9 code, Specifically
SDK9.2
•
Disk2net, disk2file now have the capability to turn of real-time mode. This means the if
the disk access is slow, fill pattern will not be outputted but the application will wait for
the slow disks.
•
Greater than 1024 scan are now supported, but it is not the default and has not been
thoroughly tested.
•
When using SDK9, and if unsure which version of SDK the disk module was previously
used with, e.g. SDK8, there is a simple rule to follow before use: EEVE (Double E,VE)
for Erase, Erase, set the VSN, Erase. This will remove any legacy in the User Directory
as it relates to the various Mark5 systems and version of SDK.
•
New version of SSErase that supports Mark5A/B/B+/C, please execute SSErase –h to get
the new default parameter settings.
•
SSErase only supports conditioning a single disk module at a time

•
The greater than1024 scan in the user directory is not working properly and will be fixed
•
Disks greater than 2TB, e.g. eight 3 TB disks, will result in only 16TB of usable storage.
Firmware supporting this capability will be added to the web site shortly. The problem
has been identified by Conduant and XF2/V100 firmware is available. Amazon firmware
was under test during release of this software.
