Internal Disk sizes no external

Midrange Systems Unix — Wed, 18 Feb 2004 13:45:44 GMT

I know that if I run the diskinfo command on a HPUX system I will recieve disk information. I need to write a script that will only pick up disk info on internal disks and not get any information on any of the external disks on the server. If I use ioscan i can only get the harware adress and the disk type if I exclude external disks. Let me know if you hav Lan awnser.

You will need to have your script identify the internal BUS's for each type of server.

There is really no way to do this in a portable, non-specific way. Even using hardware paths is "iffy" because on some boxes the internal SCSI bus also has an external connection so that there is no way to determine if such a disk is external or internal.

If you have more than one volume group, one for internal disks, and another for external disks, this would be your best approach to differentiating between them. If they're all in the same volume group, I can't think of a easy way to separate them. The SCSI protocols don't really differentiate between internal and external. It is entirely ordinary to have both internal and external disks on the same SCSI chain.
