ioscan -k does not display all the disks configured

listing — Sat, 20 Dec 2008 06:05:15 GMT

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 ??

what is your server model and where is the disks? attached disk or SAN disk? if SAN, what is the model of SAN?

why you do not use these options

ioscan -funC disk .

this will gives you all the current disks on the server

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.
