For LVD SCSI, the maximum length for a single device on the SCSI bus is 82 feet (25 meters). SCSI bus not properly terminated (see SCSI Installation problems ). Termination: If one of the ports on the device is not connected to another SCSI device, the port must be terminated. A single-ended SCSI host bus adapter severely degrades performance. have a peek at this web-site
top Backup type Each type of backup has its own impact on performance, depending on how well it can keep data streaming to the tape drive. Lots of small files require the disk to perform many random accesses instead of a continuous read. When fully used and assuming that the connection to the disks does not force the speed to a lower parallel SCSI type, an Ultra 2 (80) connection barely provides enough bandwidth for an Ultrium 448 tape drive. Before installing a driver, make sure it is not in conflict with the application software. http://www.ibm.com/support/knowledgecenter/STCMML8/com.ibm.storage.ts3500.doc/opg_3584_a69m4bfs0.html
Performance impact of various file sizes Average file size Performance impact Recommendations <64 kb: small files POOR. The mini-SAS connector on the tape drive is keyed at location four, which is the standard location for end devices. Be especially aware of monitoring applications, such as anti-virus software, which check every file that is read.
View device and drive error logs. Your cache administrator is webmaster. Upgrade to Fibre Channel if using LTO-3 or LTO-4 tape drives. If the RMI web page does not display, ping the device’s IP address.
Verify that the proper device driver is installed for the SAS host adapter. Ibm Lto 5 Tape Drive Error Code 6 Second code - the main error code (89 in this example). LTO-3, LTO-4: POOR. Refer to the manual that came with your host adapter for installation and troubleshooting instructions.
When fully used, an Ultra 320 SCSI connection can provide enough bandwidth for the following number of tape drives, assuming 2:1 compression: LTO-2: 2 LTO-3, LTO-4: 1 Ultra 320 is an excellent transport medium, but only has enough bandwidth for one LTO-3 or LTO-4 drive per bus. If the LED is not lit, the device is not communicating with the LAN. Use the equivalent on a RISC or other type of processor. For reliable operation, do not use a SAS cable longer than six meters.
The LCD displays an error code. Errors displayed on the front panel Problem Solution “!” in operator panel inventory display. Ibm Tape Drive Error Codes NOTE: Many backup applications use their own drivers. Use the correct type of cartridges for the operation.
Ultra 160 is a good transport medium, but does not have enough bandwidth for LTO-3 or LTO-4 tape drives. Check This Out The process of backing up files goes through many devices, from the files in the file system on the disk, through the backup server, and out to the Autoloader, all managed by software running on an operating system. This is most likely caused by a dirty drive that cannot read a tape and marks the tape invalid. Select the support ticket file in the browser.
When fully used and assuming that the connection to the disks does not force the speed to a lower parallel SCSI type, an Ultra 160 connection can provide enough bandwidth for two Ultrium 448 tape drives. For example, use a cleaning cartridge for cleaning. Make sure that the host adapter is properly seated in the motherboard slot and the operating system correctly detects the host adapter. http://orgias.org/error-code/i-o-error-codes.html If the failure follows the tape cartridge, the tape cartridge is probably at fault.
top top Service and repair Removing stuck tapes from slots NOTE: Contact an HP support representative if a cartridge is stuck in the drive. It uniquely maps to an error code. The system returned: (22) Invalid argument The remote host or network may be down.
Power cycle the unit. Also, make sure that the server or workstation is used as little as possible during the backup, and close down programs such as virus scanners, which check each file that is opened. PCI-X is preferred. Since Novell volumes may be compressed, hardware compression may lower the performance and capacity.
Also, if any SE devices are on the same SCSI bus, all of the devices on the bus slow down to SE speed, which severely degrades performance. Small file size can impact performance. Verify that the link LED on the RJ45 (LAN) connector is lit when the device is powered up. have a peek here To find the performance bottlenecks in your system, check the specifications and performance of the: Average file size File system type Connection from the host server to the disks Operating system configuration Backup server Backup type Connection from the host server to the Autoloader Media Average file size The hard drive must seek to the position of a file before it can start reading.
RMI network connection issues Problem Solution RMI cannot connect to the device Verify that the device is connected to the LAN with an Ethernet cable. They usually include many disks, which improves bandwidth. The system returned: (22) Invalid argument The remote host or network may be down.

If the average file size is less than 64 kb, HP recommends that you use a sequential/image backup that backups the hard drive or LUN image instead of the individual files. Check your software provider's website for the latest drivers and patches. Figure 1: Removable Storage service Right-click Removable Storage again and select Properties. If possible, do NOT use a file-by-file backup method.
do not have the extra features needed to manage the bandwidth requirements of the faster tape drives and should only be used to test basic functionality. Replace the magazines.
