Win server not compressing hp ultrium tape drive

Greetings - Regarding Win 7 machines connecting to Netware 4.11, you need to setup TCP/IP on the server and connect Windows 7 via TCP/IP.

Regarding print servers, the tried and true HP Jetdirect Print Server series are well supported with Netware 4.11

Regards and Thanks for using Fix Ya.

The L&TT support ticket contains drive configuration information such as whether hardware data compression is enabled or not.
Use L&TT to pull the ticket then look in the Drive->Drive Configuration section for details.
Here's an example:
|__ Drive
||__ Data compression : Enabled
||__ Current block size : Not available
||__ Detect WORM tampering : WORM not supported
||__ Reads after WORM tampering : WORM not supported
||__ Media removal (software controlled) : Allowed
If data compression is not enabled then it is likely that it has been turned off by the backup application. Check the options in your application to ensure that software compression (done by the server) is turned off and hardware compression (done by the drive) is turned on.
Data compression can be turned on in the drive by

• The application ( the application will usually override the drive configuration so configuring the application correctly is of prime importance)
  
• Resetting the drive
  
• Power cycling the drive
  
• Using the L&TT Set Drive Configuration utility (use the options to enable compression -see the L&TT user guide below)
  

NetBackup usersCaution NetBackup will turn off hardware compression in the drive at the end of each backup, so when you look at it with Library and Tape Tools it will be off. This is actually normal for NetBackup, so please check the configuration of NetBackup to make sure that compression is configured correctly. In this case see 'Measure Compression Ratio' (go back one level) as that will show whether compression has been in operation in the drive.

Try to reseat the controller from the PCI slot.
Reseat the SAS cable.
Here are the drivers you may need:

update your SCSI controller drivers and power cycle the server

Hi,
The low throughput may be because of many factors. Check the below factors.. It could improve your throughput.
1. Restart and disable any antivirus firewall on both backup server and client. The network utilization should be more than 20% in the master backup server. Just to make sure there is no hinderence to data flow, try copying a single big file (a 1Gig ISO file will do) from any server to backup server, the network utilization should shoot above 10% then. And will vary to 20%. If it is steadt @ 8 or 10% then firewal is the culprit. Disable it.
2. Team 2 or 3 NICs in the master backup server. Teaming at the client will also help.
3. Check the total size of data to backup, and the average size and number of files to backup, if the average size is in the range of KBs and the number of files is very high. Then only the 'Flash Backup Liscence" will only help.
Please come back and post the ratings for my solution if it turn to be of any use to you. Thnx

are you using the correct cable for the drive - it needs to be the correct cable that came with the drive - also is it terminated

Hi,

if you "have not" using Backup Software (e.g. Symantec Backup Exec, CA), you can try this IBM LTO-4 driver for Win2K.

what software are you using? try not backing up the system state to see if that changes anything?

Hardware compression is more efficient and faster than software compression and under normal constancies you won't want to do that. Having said that if your drive allows it you would need to download and install a software utility made by your tape manufacturer. That what you will use to turn off that functionality; not a setting on the PC or the backup software. Bottom line is you will need to talk to IBM support. Probably not the answer you wanted to hear but I just went through this with HP a few months ago. They have a general purpose utility that turns off the hardware compression, does a drive analysis, a cheapo write current alignment, firmware update and a few other neat tricks.
