We had our DLT drives swapped out for LTO1 drives last November and set up the cleaning in the library (STKL180) as per usual, the drives would never ask for a clean. By January we where getting massive amounts of tape errors on a daily basis, after weeks of IBM/STK trying to work out why, for the hell of it I cleaned the drives manually and instantly 95% of the errors went away. Since then I've now set up some timed scripts in TSM to clean the drives on a weekly basis. We are still getting some error's like this :-
15/04/2003 09:30:10 ANR9999D pvrntp.c(6207): ThreadId<26> BLOCK LOCATE ERROR, VOL=001010, DRIVE=TAPE0 (mt20.1.2.3): Expected BlockID 2145678; actual locate 0. And are hopeing a firmware upgrade will possibly help this. -----Original Message----- From: Karel Bos [mailto:[EMAIL PROTECTED] Sent: 25 June 2003 08:12 To: [EMAIL PROTECTED] Subject: Re: Interesting LTO fault's symptom Hi, Just to join. Today one of the tapes got a write error. In the AIX error report we found this: Description TAPE OPERATION ERROR Probable Causes TAPE User Causes MEDIA DEFECTIVE DIRTY READ/WRITE HEAD To be sure I got the drive details: Drive Usage Statistics Loads 5719 Unloads 5719 MB written 139338803 MB read 1437640 Cleanings 251 Power on hours 8590 Interesting part is the number of cleanings. Our cleaning tape has been used 19 times in the past 3 years. This drive is a replacement drive put in our library by IBM to replace a drive with a tape stuck in it.
