Creating a LOG File
If you do not want to have a log file created, delete the /LOG= portion of the
command. Substitute the name of the program you want to run after the /TASK=
portion of the command, such as DILX if you want to run a test without going
into the controller’s CLI.
Using the /LOG= qualifier creates a log file of your CLI session when you create
your HS array controller’s configuration. You are instructed to log out of the
session and print the file after the configuration is defined. Keep this file handy
at all times. Each time you alter your controller’s configuration using the CLI,
ALWAYS use the /LOG= qualifier to maintain a record of configuration changes.
Note
When accessing the CLI from more than one source, CLI commands
entered concurrently are handled by the firmware sequentially.
Refer to Appendix B for detailed descriptions of the CLI commands.
Loading the FYDRIVER for OpenVMS VAX
Creating a virtual terminal connection from a host terminal under the OpenVMS
VAX operating system requires that the FYDRIVER be loaded. The following
error indicates that the FYDRIVER has not been loaded:
%HSCPAD-F-DRVNOTLOAD, FYDRIVER not loaded
-SYSTEM-W-NOSUCHDEV, no such device available
If you receive the error message, load the OpenVMS VAX FYDRIVER as follows:
$ MCR SYSGEN
SYSGEN> CONNECT FYA0 /NOADAPTER
SYSGEN> EXIT
$
Once the driver is loaded, you may make the virtual terminal connection as
described in this section.
VAXcluster Console System
You can attach a VCS to any HS array controller. If you are unfamiliar with VCS,
refer to the VCS Software Manual for complete instructions.
8.3.2 OpenVMS VAX Support
Earlier Version OpenVMS Operating System Device Size Limitation
HS operating firmware (HSOF) (beginning with Version 1.4) supports up to 14
member RAID level 0 stripesets or RAID level 5 RAIDsets. However, OpenVMS
VAX Version 5.5–2 (and earlier) operating system versions do not support disk
device capacities larger than 16,777,216 blocks (about 8.5 GB) as file-structured
devices. This must be considered when creating HS array controller storagesets
for use with these OpenVMS operating system versions. Do not create storagesets
above this limit, for example, do not create stripesets of more than two RZ74 disk
drives because three RZ74 disk drives have a capacity of over 11 GB.
CAUTION
Exceeding the 8.5 GB limit can cause data corruption without prior
warnings to the user.
