Problem Solution
What happens if a
drive fails and there
is no active spare? HP recommends that at least one drive be assigned as a global active
spare at all times. If a drive fails and no active spare is present, system
warnings alert you that a drive failure occurred and that the logical drive
(RAID set) is in a critical state. Although the system continues to rebuild
and serve files without interruption, there is a much greater risk of data
loss in this state. The drive replacement kit provides detailed instructions
for installing replacement drives, rebuilding the critical RAID set, and
assigning an active spare.
How do I
communicate with
the system without a
network connection? The HP NAS VA has a serial TTY connection that can be used to access
the system without a network connection. To use it, connect the TTY port
to another computer using the supplied serial cable. A terminal emulation
program can then be used to interact with the system's menu-driven
console interface.
How do I create UNIX
mount points? The HP NAS VA automatically generates a UNIX mount point at the root
of a logical volume when you create the volume. Thus, there is no need
to manage mount points on a directory by directory basis. Refer to your
UNIX users guide for more information about mount points.
I cannot get guest
access to CIFS
shares. By default HP-UX uses a negative value UID/GID, e.g., nobody = -2.
CIFS/9000 should mask this by creating a user called "smbnull" which
has a positive UID/GID.. If it is not there, you should use a guest user
name "nobody" and make sure it has a positive UID/GID. Check for
negative value UID/GID in user accounts in etc/passwd and change
to a positive value.
I am having general
storage setup
problems, e.g., my
array won't initialize. Make sure your HP VA7100 and/or VA7400 have firmware HP11 or later
installed.
After adding a
software patch, I am
having trouble with
my system. This HP-UX operating system has been optimized and modified for the
HP NAS VA solution for better file serving performance and
manageability. Any patches or modification to the operating system that
are not listed on the HP NAS VA support website will not be supported.

Status tab and navigate the System Status logic tree to System
