I am in the process of installing a rz29b 4.3 Gig disk on an Alphaserver
1000 and have a couple of questions. While checking the archives I found
several references to the speed of the rz29 as 7200 rpm but when I labeled
the disk (see label below) the speed is 3600. This was obtained from the
standard /etc/disktab entry for a rz29b. Do I have to edit the disk label
and change the speed to 7200? Or is this disk really spinning at 3600 rpm?
Can I create a single advfs (or ufs) 4.3G file system on this disk or do I
have a 2.1G limit? I am running DU 3.2c.
