- As far as I can judge, the hp 97560 disk is equivalent to the "officially"
- (on a 9000/817) supported disk C2474S. Both are 1.35 GByte, have same access
- times, etc. Only the price is different: the C2474S is more than two times as
- expensive as the 97560.
-
- So I decided to buy two 97560 disks... But I had a hard time hooking 'm to the
- 9000/817 (hpux 8.02). I could run "mediainit", "dd" and even "diskinfo" with
- the disk, but no way to run "newfs" or "mkfs". It just would die with a write
- error.
-
- The final solution to this problem involved three steps.
-
- (1). Rename (or copy) the disktab entry for C2474S to 97560-300. (The string
- "97560-300" is returned by the "diskinfo" program.)
-
- (2). Take an emacs (or any other editor capable of processing binary images)
- and start editing the kernel /hp-ux !!!! Replace (in overwrite mode) the
- strings "C2474S" and "C2474S_sizes" by "97560-300" and "97560-300_sizes"
- respectively.
-
- (3). Reboot.
-
- Only after performing these hacks I managed to run "newfs" on the 97560 disk...
- The 817 has been up and running with the 97560 disks for almost a week now,
- without any problems. I also performed the above mentioned step (2) on the file
- /etc/conf/lib/libhp-ux.a so that building a new kernel automatically
- incorporates the 97560 entries in the kernel tables.
