Linux-UNIX: Upgrading A-TAP in Zones and WPARs environment

Procedure

For Solaris Zone:
1. On the master/global-zone, remove the previously installed K-TAP device.
```
zoneadm -z <zonename> halt 	 	
zonecfg -z <zonename> 	 	
<zonename>> info
```
2. If a K-TAP device is found, remove it.
  
  /<zonename> remove device match=/dev/ktap_xxxx (for Solaris 10)
  /<zonename> remove device match=/dev/guard_ktap (for Solaris 11)
```
 	 	 	 	
<zonename>> verify 	 	
<zonename>> exit 	 	
zoneadm -z <zonename> boot
```
3. For Solaris sub-zones, remove the previous K-TAP device file and link from sub-zone device directory. Go to the sub-zone device directory, for example /export/home2/zones/iris3/dev.
```
cd /export/home2/zones/iris3/dev 	 	
rm -f ktap_xxxx guard_ktap
```
For Solaris Zone:
1. On the master/global-zone, add the new K-TAP device to the zone configuration:
```
zoneadm -z <zonename> halt 	 	
zonecfg -z <zonename> 	 	
<zonename>> add device
```
  <zonename>device> set match=/dev/ktap_xxxx (for Solaris 10)
  <zonename>device> set match=/dev/ktap_xxxx (for Solaris 11)
```
<zonename>device> end 	 	
<zonename>> verify 	 	
<zonename>> exit 	 	
zoneadm -z <zonename> boot
```
2. Add the guard_ktap link and change permission. Go to the sub-zone device directory, for example: sub-zone device directory=/export/home2/zones/iris3/dev
```
cd /export/home2/zones/iris3/dev
ln -fs ktap_xxxx guard_ktap 	 	
chmod 0666 ktap_xxxx 	 	
chmod 0666 guard_ktap
```
3. Since there are multiple ktap devices, repeat steps for each K-TAP device by using the name ktap_xxxx_x(solaris 10) or guard_ktap_x (solaris 11)
For AIX WPARs: on WPARs, change permission on K-TAP devices. Go to the WPARs device directory, for example: wpars device directory=/wpars/odin3/dev
```
ln -fs ktap_xxxx guard_ktap 	 	
chmod 0666 ktap_xxxx 	 	
chmod 0666 guard_ktap
```
