HP LTT 4.10 for Solaris 10

How to pull a dump from a HP LTO drive using HP’s LTT 4.10 command line on Solaris 10:

You must first do a scan on the system to save them into the “saved_scan.txt” in the default install dir of the LTT tool. As long as no system changes are made (IE no drives added or removed from the system) then you should never have to do the scan again. The syntax of the command is “hp_ltt –f scan”. No other options are needed. You should do a “cat saved_scan.txt” to verify that the drives are seen by the LTT tool.

Once the drives are seen you must use the ticket option to get the support ticket or dump off of the drive. You have to get the path of the drive correct or it will not pull the dump from the drive successfully. This exact path is in the “saved_can.txt” file. No other options are needed and this will save the drive dump in the default “logs” dir of the LTT tool.

Note:
Below is an example of the command used that successfully pulled a dump in the correct .lzt format from a drive.

bash-3.00# hp_ltt -f ticket p=/pci@1e,600000/pci@0/pci@2/SUNW,qlc@0,1/fp@0,0:::0.1115392.0[st@w500104f000acb624,0-/dev/rmt/0]:HP:Ultrium 4-SCSI:H58S

And then here is an example of the file that was placed in the logs dir.

bash-3.00# ls
Database_config.cfg
EventLog_backup_1.ltt
EventLog.ltt
prl.txt
st_HPUltrium_4-SCSI_20100824_113715_HU18031635.lzt
toolactivity.log

At this point the customer should just grab the .lzt file and e-mail to the engineer that asked them to get the dump off of the drive.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Work can be restarted on the drive that had the error information taken.
