ioscan -k does not display all the disks configured

Hi,
ioscan -k does not display all disks that are physcially presnt.(some are left out) But without -k all the disks are displayed. I saw the man page which refers to -k will display only kernel i/o hardware tree. How can i make the disks being displayed consistently with ioscan -k command.

This is the author again..
ioscan -k lists the devices some times all of them . and some times leaves out some of them. I mean the o/p is not consistent.

No hot plugging / removing has been performed on the system. I am talking about 11i.v3. what could be the reason ??

Hi,
The complete ioscan command is "ioscan -knC disk". The problem is gone after a reboot. But i just wanted to know if this is a problem at all. Thanks all for the inputs.

No. Using -k is the wrong option if you want to know about all possible disks, vs the ones the kernel knows about.
Rebooting makes them consistent.
