Hello All,

I don't understand why I don't see the following when I enter the "/etc/ioscan -kC disk -m dsf" cmd ? :
/dev/rdisk/disk5_p1
/dev/rdisk/disk5_p2
/dev/rdisk/disk5_p3

I listed the output from my "idisk /dev/rdisk/disk5" cmd @ end of this message.

Commands I ran :

EFI 500MB

please try once the command
#insf -e -C disk
and see the O/p of the #ioscan -kfnNCdisk

The EFI,HPUX and HPSP ptns have already been created .

#ioscan -kfnNCdisk must show u the device files that u r wishing for, they have already been created but the option -N of iosacn shalll shpow this for u.

u can check that persistent DSFs have got created using the command as

#lssf /dev/disk/disk5_p1
#lssf /dev/disk/disk5_p2
#lssf /dev/disk/disk5_p3


also u can do

#ll /dev/disk/disk5_p1
#ll /dev/disk/disk5_p1
#ll /dev/disk/disk5_p1


the Persistent DSFs have been created but the ioscan -fnNCdisk that is -N option shall show u the persistent DSFs.

Hi Jerry,


u can also refer to the manpage of the ioscan command there are lot many added option as of 11iv3.

More than that -N option for Persistent DSFs has been added to the commands like vgexport and vgimport also and vgscan etc also
