General Configuration Commands
Upgrade the HP VMA SAN Gateway Software
The syntax for the upgrade command is:
cluster upgrade <url or image name> immediate | rolling |
staged
This command upgrades the software, taking the image from the URL or image
name source. See Key to Command Parameters on page 120 for valid URL
formats.
The immediate parameter causes all of the Gateways being upgraded to reboot
immediately.
The rolling parameter upgrades and reboots each gateway one at a time. Rolling
upgrades can only be done when upgrading between releases that differ by minor
version number; for example, upgrading from version 5.1.0 to version 5.1. x , where
x is 1, 2, 3, and so on. Rolling upgrades from one major release to another (for
example, 5.1.0 to 5.2.0) are not supported.
The staged parameter causes the cluster to be split into two clusters, A and B,
with half the HP VMA SAN Gateways in cluster A and half in Cluster B. The HP
VMA SAN Gateway(s) in Cluster B are upgraded first, followed by those in
If you omit the ":password" part, you may be
prompted for the password in a follow up prompt,
where you can type it securely (without the
characters being echoed). This prompt will occur
only if the "cli default prompt empty-password"
setting is true; otherwise, the CLI assumes you do
not want any password.
If you include the ":S" character, this is taken as an
explicit declaration that the password is empty, and
you will not be prompted in any case.
INTERACTIVE A command that is only available for interactive
usage from the CLI shell. Specifically, this excludes
using the command from jobs, because the
Scheduler runs commands in a batch mode with no
direct user interactivity. In most cases, it is obvious
why each of these commands has the
INTERACTIVE restriction.
