Procedure to add the new disk to Solaris Zone..

By default it is not possible to add raw device to zone without taking a reboot on zone, but here is some cool stuff for usage to avoid the downtime.

I found a little hack to accomplish the objective of adding raw device to zone without rebooting it. Here is a way out - 

1) Add the device to the zonecfg 

#zonecfg -z barvozone1
zonecfg:barvozone1> add device
zonecfg:barvozone1:device> set match=/dev/rdsk/c3t60050768018A8023B8000000000000F0d0s0
zonecfg:barvozone1:device> end

2) use the mknod command to create the device in the zones dev folder

#ls -l /dev/rdsk/c3t60050768018A8023B8000000000000F0d0s0
lrwxrwxrwx   1 root     root          67 Feb 18 15:34 /dev/rdsk/c3t60050768018A8023B8000000000000F0d0s0 -> ../../devices/scsi_vhci/ssd@g60050768018a8023b8000000000000f0:a,raw

#ls -l /devices/scsi_vhci/ssd@g60050768018a8023b8000000000000f0:a,raw
crw-r-----   1 root     sys      118, 128 Mar  5 23:55 /devices/scsi_vhci/ssd@g60050768018a8023b8000000000000f0:a,raw

# cd /barvozone1/zonepath/dev

# mknod c3t60050768018A8023B8000000000000F0d0s0 c 118 128

That's it. The raw device is now visible within zone and now you can start with your stuffs without any downtime. Isn't it cool?
