Hp Ultrium 1840 Sas
2012-08-13 Every time we insert a backup tape into the drive, regardless if it's LTO 3 or LTO 4, the drive returns the "Tape Error" flashing light. Here are some details to help you understand our problem: Tape Drive Model: HP StorageWorks Ultrium 960 Connection: Bridged SCSI from external tape drive "1" (which is working completely fine) Backup Management Software: Symantec Backup Exec hp 1840 sas Here's when the problem started. Prior to this, everything was working fine. We have 2 external HP tape drives. We normally only use LTO 4 tapes for External Tape Drive (ETD) 1 and LTO 3 tapes for ETD 2. One morning before having my coffee, I inserted a LTO 4 tape into ETD 2, which produced the above mentioned error. Here is what I have tried so far: - reset the tape drive - delete and re-added the tape drive from Symantec Backup Exec - rebooted the server running Symantec Backup Exec I do not know what else to try besides re-installing Symantec Backup Exec. Any other suggestions? Thanks in advance. 0 Question by:Benny9 Facebook Twitter LinkedIn Google Best Solution byBenny9 chakko: Thanks for your suggestions. Unfortunately, none of them work.

Dave Mitchell takes a look at eight of the latest drives and sorts the wheat from the chaff HP StorageWorks Ultrium 960 Image 1 of 6 There's no denying the LTO format has delivered on every promise so far and that LTO-3 is currently the fastest on the market. This particular drive is the main reason we elected to use a separate fibre channel (FC) disk array https://www.experts-exchange.com/questions/27479567/HP-External-Tape-Drive-Error.html as it was the only way to allow it to stream properly. The quite stunning native transfer rate of 80MB/sec is never going to be achieved when backing up from a local disk drive and to prove this we also ran tests on the server's local storage sub-system.
Running the performance tests using data on the FC array saw ARCserve report an amazing 79.3MB/sec for backup. The disk to http://www.itpro.co.uk/87753/hp-storageworks-ultrium-960 tape verification and data restoration tasks were also impressive with these returning 72.5MB/sec and 69.4MB/sec respectively. Backing up the test data from a local hard disk saw these speeds drop by nearly 20 per cent. However, even here the backup speeds are still faster than Quantum's new DLT-S4 which has a native transfer rate of 60MB/sec.
Storage is extremely good as the solid LTO-3 cartridges offer a native capacity of 400GB while backward compatibility extends to reading both LTO-2 and LTO-1 cartridges and writing to LTO-2. As defined in the LTO specification the drive incorporates many of the best features found across a wide range of formats. Based on 1/2in linear recording technology the drive uses a thin film/magneto resistive head and the media is held in a single reel cartridge that borrows many features from DLT (digital linear tape) in its quest to provide a stable tape path at high speed. In keeping with current data archiving regulatory demands WORM (write once read many) also comes into the picture. HP uses the 4KB Flash memory chip built in to all LTO cartridges to stop data being overwritten. However, because the WORM cartridges have their servo tracks encoded differently, you still have to pay extra for th

When I log into the ESX via ssh hp storageworks I see in my backup logs: MACHINE/MACHINE-flat.vmdk/bin/tar: /dev/nst0: Wrote only 0 of 262144 bytes/bin/tar: Error is not recoverable: exiting nowor/bin/tar: /dev/nst0: Cannot open: No such device/bin/tar: Error is not recoverable: exiting nowand when I do: "/bin/mt -f /dev/st0" rewind I get: "/dev/st0: No such device"The only way to fix that is to insert a clean tape and then restart the ESX server.I always insert a clean tape once a week.What hp storageworks ultrium can be the problem? 631Views Tags: none (add) This content has been marked as final.

The kernel gets a SCSI communication error to the tape device, and the only way to fix it is to reboot. Thats why alot of people (including myself) suggest pushing your backups to a windows or other linux server and make tapes there, where a reboot does not hurt you.But since you are, you should look into BRU (or some people prefer lonetar) to make your tapes. BRU will validate and do a lot that using tar will not do when it comes to data integerity.Depending on the module that is loaded, you might be able to unload the SCSI module in the kernel, and reload it. When your tape is working, do a 'lsmod'When the tape stops working, can you 'rmmod 'then reload the module? modprobe or insmodthanksron Like Show 0 Likes (0) Actions Actions Remove from profile Feature on your profile More Like This Retrieving data ...
