Cannot connect to Web Management Interface
HP D2D is not visible on the network
See
“
Connecting to the network
”
on page 152.
Cannot log in to the Web Management Interface
The password is case-sensitive, please make sure you know whether CAPS LOCK is on or off.
If you cannot find the password to the Web Management Interface login screen, it can be reset to
factory value.
1.
Ensure that there are no backup or restore jobs in progress to the device.
2.
Press the Power On button on the front of the HP StoreOnce Backup System three times in quick
succession to reset it.
3.
After approximately 5 seconds, the HP StoreOnce Backup System will begin its reboot sequence.
4.
The HP StoreOnce Backup System will be reset to factory networking settings and the Adminis-
trator password will be reset to Admin. No user data will be lost but you will need to re-configure
your network settings, because they may be reset by this action.
NFS State handle error
NOTE:
NetBIOS name resolution is not supported on CIFS shares.
The following sequence will cause problems when connecting to a NAS share.
1.
Create an NFS share and mount it on a Linux box.
2.
Delete the share on the D2D 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.
Cannot authenticate an iSCSI session
CHAP authentication is used within HP D2D. For details of the settings on the Microsoft iSCSI initiator
and the HP D2D Web Management Interface, see also the
