- Subject: VMBACKUP & 3490 Problem.
- Lines: 33
-
- We are evaluating an IBM 3490E C22 cartridge unit, but some problem
- arise when using VMBACKUP at level 5.3A.
- Our configuration is as follow :
- VM/SP Release 5.0 at put 9002
- IBM 4341-2
- 3490E channel attached to the 4341 in a 2 Mbps channel
- The 3490 is defined as a 3480 unit to VM without any feature.
-
- The problem is :
-
- When VmBackup is ready to go to next cartirdge in an full backup job
- (not a physical one) we get an unrecoverable I/O error with message
- VMBTMP540E UNRECOVERABLE ERROR OCCURRED WRITING A DATA BLOCK
- and the the unit is detached.
-
- The EREP report indicate a fault symptom code 4411 and the description of it
- is as follow : A Read Backward command has been issued for a record in 3490E
- Extended Format. A unit Check, which impacts performance, is given the first
- time a Read Backward command is issued. The Unit Check is only given once per
- tape mount.
-
- The questions are :
- Does somebody else experimented this symptom before ?
- Is the IDRC feature involved in this ? It must be active or inactive in the
- unit ?
- Can it be a VMBACKUP release level problem ?
- What is record in 3490E Extended Format ?
-
- Thanks in advance.
