Well, my customer has a TruCluster Production environment of 2
8200s and a fully loaded ESA box. They have 89 devices specified in the
storageworks box. When they wanted to greate a new ADVfs file
domain and file set, I said "well, lets use dxadvfs". MISTAKE! When I
started up dxadvfs and asked it to show the devices, the 8200 on which
I was running it virtually stopped. At approximately 30 minutes later,
the gui started coming up.
Is this normal for a system with a LARGE number of disks? This is
UNNACCAPTABLE to wait 30 minutes! If this IS normal, what is being done
to fix this, or can it be fixed?
Thanks for your help.

| 992.1 | One possibility... and a caveat | DECWET::DIPIETRO | Thu Jan 30 1997 08:56 | 23 | |
If you are running "dxadvfs" on a Gold system, there is NO HOPE of
managing a system with 89 devices.
If you are running "dtadvfs" on a Platinum system, then here's
one possibility. From the release notes:
o When there are several offline HSC devices, unmounted
filesets, or spun-down disk drives, GUI performance will be
significantly reduced. The GUI may appear to hang. Avoid
having more than a few of these devices in your system
configuration or prevent the agent from accessing them by
using the /var/opt/advfsd/disks.ignore configuration file.
See the advfsd man page.
Caveat:
The Platinum "dtadvfs" GUI will be hard pressed to handle 89 devices
in any case. The current implementation just doesn't scale that well.
There will be some improvements in Steel and a complete reimplementation
is planned in Post-Steel.
If you find the GUI unusable, suggest that you deinstall the GUI and
DAEMON subsets and use the command line interface.
