[Veritas-bu] NB3.4 x Solaris2.6 x st.conf x Error 92

Hi friends.

I would like ask you for a HELP.

- I have NetBackup 3.4 on SUN Enterprise 3500 with Solaris 2.6
- I have patch J0850482
- I have connected OVERLAND LibraryPro 2219 with follow parameters :
Product Identif :               LXB
Firmaware Revision :    04.05
Boot Version :          21
Flash Type :            AMD 29F400

- If I make the follow records in /kernel/drv/st.conf and I make boot -r,
the NetBackup 
is mounting of the tape in first drive of the LP2219 but Device Manager
doesn't detect it and after
mounting time is reported error 52 - "Status: (52) timed out waiting for
media manager to mount volume".
.
.
"SONY    SDX-500C",     "SONY 8mm AIT2",                "SONY_AIT";
.
.
SONY_AIT        =       1,0x34,0,0x9639,4,0x13,0x0,0x8C,0x8C,3;
.

- If I didn't include this records in the st.conf of the Solaris, I can
backup of the data without problem, but during the partial restore (several
files only)
or restore of the files from incremental backup I got message 92, 
10:51:15 (1994.001) /dumps/arch/arch_1_3072.arc was not restored.
10:51:15 (1994.001) /dumps/arch/arch_1_3073.arc was not restored.
10:51:15 (1994.001) /dumps/arch/arch_1_3074.arc was not restored.
10:51:15 (1994.001) INF - TAR EXITING WITH STATUS = 92
10:51:15 (1994.001) INF - TAR RESTORED 0 OF 0 FILES SUCCESSFULLY
10:51:15 (1994.001) INF - TAR KEPT 0 EXISTING FILES
10:51:15 (1994.001) INF - TAR PARTIALLY RESTORED 0 FILES

10:51:15 (1994.001) Status of restore from image created 
Mon Jun 11 10:40:46 2001 = media manager detected image that was not in tar
format

I understand it so, that there are problem with dynamic size of the media
block reading/writting data.

- Similar problem comes on during of the backup clon's creating. If I have
backups with MPX>1, I got error 90 or 174.
"15:04:32 INF - Duplicate of backup id uzel2_0989020381 failed, media
manager received no data for backup image (90)."
"17:20:24 INF - host qa backupid prepro_0988919280 write failed, media
manager - system error occurred (174)"
After set MPX=1 for both drives there is no problem.


- Would you be somebody very so kind and can HELP ME, PLEASE ?

Thank you very much

and best regards.
