ioscan difference

[KapilRaj]

Guys,

I tried my best but still can not make out why my ioscan -fnkC disk shows such an output.

Please note the number of device files for disk at Hardware path 0/4/1/0.0.0.1.0

output is attached.

Regards,

I suppose it would help if there was a question here but I think the answer is that you are seeing disk slices (or partitions). Were you not expecting them?

Kaps,

I'm guessing that /dev/dsk/c1t1d0 is your boot disk yes?

THis would be normal for an Integrity Server - the boot disk is split into 3 partitions with LVM or VxVM using the main partition (s2).

The other two partitions are formatted as EFI partitions - EFI is abit like the LIF area used to be on PA-RISC systems.

Yes . It is the boot disk on an Itanium based system. I am getting what you are saying. I was expecting only the traditional /dev/dsk & /dev/rdsk device files NOT the s1,s2 ....

You've got to read up on how an Itanium system works. It is different than PA-RISC and the disk slices are used for specific boot up processes.
