7. The share is now available as a network drive to be mounted from a UNIX or Linux server so
that it may be a target for the backup application.
NOTE: The share is not optimized for general purpose file storage. The HP StoreOnce Backup
System is a NAS deduplicating appliance that is optimized for backup.
Connecting to the NAS share on UNIX or Linux
To access the NAS share from a UNIX or Linux server on the network, use the mount command.
The actual syntax of the command depends upon which operating system you are using.
NOTE: See the Linux and UNIX Configuration Guide for more detailed information.
Problems connecting
The following sequence will cause problems when connecting to a NFS share.
1. Create an NFS share and mount it on a Linux box.
2. Delete the share on the StoreOnce Backup System without unmounting it from the Linux box.
3. Recreate the share again with the same name.
In this scenario, the Linux client will assign a new set of inodes to the new share, but when trying
to access the old mount point it will use the previous set of inodes and will therefore not manage
to connect.
Reboot the host Linux system and the connection will work again.
NOTE: If the StoreOnce D2D Backup system detects a possibly issue with data integrity for a
Share it will immediately set the status of that device to ‘failed-to-start’ or ‘read-only’, this is to
minimize the possibility of any further potential corruption being introduced on the device. If a
device enters one of these states it is reported on the GUI and selecting that device will give you
some options to attempt to restore the device to a working state. For more details see Recovering
devices that have failed to start or have become read-only (page 132).
