I'm setting up Sybase with async IO on HP logical volumes, and the
Sybase manual says to use the character device. But I saw somewhere
that I should use the block device when using HP logical volumes.
Which one should I use?
Thanks,
Tom

1. HP-Logical Volumes and Sybase Logical devices ?
On HP while it's not documented, you can use logical volumes instead
of pure raw partition. One of the features of logical volumes is that
ii is "soft partitionning". Hence, even after its creation, a given logical
volume can be extended.
My question is: If I can extend a logical volume on which is mapped a Sybase
device, can I then extend the device so that it includes the new disk space
just allocated to the logical volume ?
I tried to figure out in the doc how to do this by as logical volume are not
even documented, they did not documente this capability. Maybe it simply
doesn't exist.
If you have any insight ...
