Re: How to identify disk types on HP Itanium
It should give enough info to identify internal disk (obvious by address); the DVD; and which disk is EMC's.
Just a thought,
Rita

you use diskinfo command to check that

# diskinfo /dev/rdsk/c1t0d0

Re: How to identify disk types on HP Itanium
device files will not change! which is important from "System point view"
hardware path decides about the order, which nothing related "System point view" so you no need to worry. only (device file important)
Finally if satisfied with answers, D'not forget to assign points

Re: How to identify disk types on HP Itanium
Your servers has an optional P400 smart array controller, so you cannot see the disks directly, but the logical drives only.
Answered?
Hope this helps!

Re: How to identify disk types on HP Itanium
You can be sure all disks behind an FC HBA are somewhere outside.
But you cannot be sure all SCSI/SAS are internal. Same for USB.
You need to know the server and read the ioscan.
Hope this helps!
Regards
Torsten.

Re: How to identify disk types on HP Itanium
But we want to know this from the output of some command/s which can tell us dynamically which devices are SAN luns and which are local ones.
Using o/p of this command/s, some other code has to determine disks types.
Is there any such command/s?
