Explain how to configure a system to boot from a SAN device..explain the differece between TDC and XFC

[Martin Hughes]

For how to boot from a SAN device, see WWIDMGR user's manual;

TDC is a performance analysis tool, see;

XFC is Extended File Cache, which is part of the operating system, see OpenVMS System Managers Manual Volume 2 (section 4);

If you have access to the VMS documentation set, I suggest that you read that; your question regarding "SAN booting" is so vague as to be borderline unanswerable in this forum.

There is probably no commonality whatsoever between TDC and XFC; TDC ("The Data Collector") collects data, typically for performance analysis; XFC (eXtended File Cache) is a shim in the file system that acts as a file cacher (not a logical block cacher, as several 3rd parties provide).

Dear Rob,

Hi,

you will need to know about wwidmgr, so that you can configure your system to boot from SAN. The wwidmgr manual is available here:-

ftp://ftp.digital.com/pub/DEC/Alpha/firmware/archive/doc/wwidmgr_v13.pdf

Other important documentation is available online from the main documentation site:-

http://h71000.www7.hp.com/doc/os83_index.html

Pick the tab that is appropriate to your version of OpenVMS.

You will find that the V8.3 installation and upgrade manual has a good section on booting from SAN.
