8 Troubleshooting Use the information in this chapter to troubleshoot problems. More detailed troubleshooting information can be found at http://www.hp.com/support. This chapter provides troubleshooting information on: • Connecting the hardware (page 50) • Connecting to the HP StoreOnce Backup System from the backup application (page 50) • Connecting to the network (page 50) • Using the 10Gb ports (page 51) • Performance (page 51) • Power On/Off problems (page 52) • Cannot connect to Web Management Interface (page 53) • Cannot connect to NAS share (page 53) • Cannot access a storage shelf (page 53) Connecting the hardware Please see http://www.hp.com/go/connect or http://www.hp.com/go/ebs for supported network cards, cables and physical tape drives. Connecting to the HP StoreOnce Backup System from the backup application Make sure you have the latest version or software patches for the backup application. Please see http://www.hp.com/go/connect or http://www.hp.com/go/ebs 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. • Make sure that the iSCSI initiator is connected to the devices and log on to them, if they are not, see Targets tab (page 38). • If it is not accessible, rerun Discovery. NOTE: There are practical limitations on the number of devices that each host and FC switch or HBA can access. It is possible to configure more drive and library devices than a host can access. See the D2D Best Practices for VTL, NAS and Replication implementations for maximum and recommended values. Connecting to the network NOTE: If you have selected the Link aggregation mode, ensure that switch is configured correctly at the other end. If you cannot access your device on the network, please check the following: 1. Regardless of the network configuration mode and interface type, please ensure that there is a CAT-5E (or above) Ethernet cable connected to network port 1 (HP D2D4100 Series and HP D2D2500 Series) or network port 3 (HP D2D4300 Series). This is the primary port for communication to the Web Management Interface and, on SCSI models, the primary port for 50 Troubleshooting
