3.4 Running VMSINSTAL.COM
3.4.4 Selecting the Destination
The destination parameter is optional. By default, VMSINSTAL.COM
assumes that the product is to be installed in the system common directory
SYS$COMMON on the system disk. However, you must use this parameter in
the following two instances:
• To install the product in an alternate root. The product is installed on a
system disk other than that on which the target system is running. Specify
the alternate system root in the following format:
device:[SYSn.]
where:
device The device on which the alternate root resides
SYSn. The top-level directory of the alternate system root
You can also specify a previously defined logical name for the alternate root.
• To copy the product kit save sets into a storage directory for later installation.
For more information about the Get Save Set option, see Section 3.6.3.
Specify the destination directory in the following format:
device:[directory]
where:
device The destination disk device
directory Usually a directory dedicated to product save sets on the specified disk
3.4.5 Verifying, Logging, and Confirming the Operation
The VMSINSTAL.COM command procedure includes a BACKUP command that
copies the save sets to the destination directory. You can verify, log, and confirm
the copy operation by specifying BACKUP qualifiers with the VMSINSTAL.COM
Get Save Set option. See Section 3.6.3 for more information.
3.4.6 Completing the Installation
When the installation is complete, VMSINSTAL.COM performs one of the
following actions, depending on the requirements of the product you have
installed:
• Performs an automatic shutdown of the system; you might be instructed to
reboot manually.
• Returns you to the system prompt.
When the product is installed, back up the updated system disk. For instructions,
see Section 11.17.
3.5 Recovering from a System Failure
If the system fails during installation of an update or optional software product,
VMSINSTAL.COM attempts to continue the installation upon rebooting.
Depending on when the system failed, one of three conditions exists:
• The system disk was not altered before the system failure. In this case,
VMSINSTAL.COM instructs you to restart the installation.
