tar HP->AIX

[Thomas Braeutigam]

Hi
we want to know something special:
1st Where to determine the default
setting which has been used while writing
on the hp.
the tar -w command was directed towards
/dev/rmt0 a 4mm DDS3 drive.

2nd
How to read this on AIX 433 with DDS3
drive.

(probably there is also a testing method
for the blocksize with dd -command.
)
THANKS

Are you talking the default tar settings for write? If so, I do not believe that HP (or any other UNIX OS) has a default setting. Reading the tar tape on AIX should be no different. The tar command is pretty much the same, the exception being GNU tar but then you have additional options.

On Hp , Have you created a tar backup with a block size e.g. tar -cvbf 64 etc..
If so what you need to do on AIX is check if you have the block size set for the tape drive ( lsattr -E -l rmt0 ) if the block size shows 0 ( then this is variable) so you should be able to read it , but if you have it set to 512 or something else , it may may be best to change it to 0 and then try reading it .

Thomas,

Setting the block size to zero usualy sorts out problems reading tapes on AIX. Use the command:

chdev -l rmt0 -a block_size=0
