Multiple users, Timeout problems with nas cifs shares – HP StoreOnce Backup User Manual
Page 174
To continue using these features, separate licenses must be purchased for StoreOnce Catalyst and
Replication and applied within the 90 day period. If they are not, data is not lost but:
•
Replication: Replication Target libraries will continue receiving replicated data, however, you
will receive notification every 24 hours that your license has expired.
•
Catalyst: Catalyst stores will still be available as target devices for backup, however, you will
receive notification every 24 hours that your license has expired.
Use StoreOnce CLI commands to show the current license status and apply the demo and individual
licenses. See the HP StoreOnce Backup system CLI Reference Guide and
for more information.
Multiple users
The HP StoreOnce Management Console supports multiple GUI and CLI sessions. However, we
recommend:
•
No more than 8 active Operator sessions for the GUI
•
No more than 16 active Operator sessions for the CLI
•
No more than 1 active Admin session to ensure there is no confusion when configuration
changes are made
Currently, you cannot see which users are logged in. The accounts show command will list all
the user accounts defined for the HP StoreOnce Backup system. For each account the authority
level is provided.
Connecting to the StoreOnce Backup system from the backup application
Make sure you have the latest version or software patches for the backup application. Please see
for supported applications.
Stop and restart the backup application services after the backup device has been discovered. If
you still cannot access the device, check Device Manager to make sure it is accessible from the
host.

For Fibre Channel devices: Models with an 8Gb Fibre Channel card have a theoretical limit
of 255 devices per Fibre Channel port on a host or switch; models with 4Gb Fibre Channel
card have a theoretical limit of 127 devices per Fibre Channel port on a host or switch.
NOTE:
There are practical limitations on the number of devices that each host, Fibre Channel
switch, or HBA can access. It is possible to configure more drive and library devices than a host
can access. Although the Fibre Channel connection supports a greater theoretical number of devices
per Fibre Channel port on a host or switch, HP recommends that no more than 64 devices are
configured for use by a single host.
Timeout problems with NAS CIFS shares
By default, Windows CIFS timeout is set low for NAS backup implementations. This can lead to
various error message related to lost connection to the share, unrecoverable write errors or timeout
problems resulting backup job failures. It is recommended to add or to increase the “SessTimeout”
value from the default of 45 (seconds) to 300 (five minutes).
By increasing the timeout, it ensures that the Windows CIFS timeout does not cause your backup
application to prematurely timeout the running job.
NOTE:
This can resolve issues resulting from timeouts, but is not exclusively the only reason for
such failures. A large number of ‘out of sequence’ writes causing slow response times within the
product often can be the root cause. Further analysis may be required should increasing the timeout
not be successful.
