- We have installed these disks on 9000/730 running 8.07, and this
- is how do do it. You can find out the alias for the disk like this:
-
- isaac % /etc/diskinfo /dev/rdsk/5s0
- SCSI describe of /dev/rdsk/5s0:
- vendor: SEAGATE
- product id: ST42100
- type: direct access
- size: 1900538880 bytes
- bytes per sector: 512
-
- Where the disk is at SCSI ID 5.
- The product ID is the alias. In /usr/sam/lib/disk_aliases, put the following:
- ST42100 SEAGATE_WREN9 scsi single_ended_scsi
- Thus, sam will look for an entry in disktab with the name SEAGATE_WREN9.
- On our machine, the entries look like this:
- SEAGATE_WREN9_noswap:\
- :No swap or boot:ns#48:nt#15:nc#2568:\
- :s0#1848960:b0#8192:f0#1024:\
- se#512:rm#3600:
- SEAGATE_WREN9_noreserve:\
- :No swap or boot:ns#48:nt#15:nc#2568:\
- :s0#1848960:b0#8192:f0#1024:\
- se#512:rm#3600:
- SEAGATE_WREN9:\
- :No swap or boot:ns#48:nt#15:nc#2568:\
- :s0#1848960:b0#8192:f0#1024:\
- se#512:rm#3600:
-
- SAM works like a charm after this. I am not familliar with the 800 series,
- but I hope this helps.
- P.S. The numbers for the disktab are from the output from a DEC using
- rzdisk. Anyone know of an HP program that gives similar output ???
- When you are all done, it should look like this.
