Cronjob for Virtual I/O Server with Fix Pack 8
-----------------------------------------------
The cron function was introduced to the padmin shell in VIOS 1.3 (fix pack 8). However, many commands fail when run from cron, even though they work when run from the CLI. Failing commands include mount <NFS directory> and backupios.
This is because /home/padmin/.profile is an important part of the CLI, changing the path and aliasing many commands. cron does not read a user's .profile, and so the commands fail. This is working as designed.
To enable cron to run commands in the same way as the CLI, the command should start with
/usr/ios/cli/ioscli
For example:
/usr/ios/cli/ioscli mount nimserver:/export /mnt
/usr/ios/cli/ioscli backupios -file /mnt/vios_backup -mksysb

The following example creates an SEA that maps the physical Ethernet adapter ent0 to the virtual Ethernet adapter ent2, using ent2 as the default adapter and 1 as the default VLAN ID. The IP configuration from the interface en0 is migrated to the interface en3 of the generated SEA.

»Run the command:
$ rmtcpip -interface en3
Parameters to be reset:
Host name: No
Name server: No
Effective immediately: Yes
Routing: No
Answer y to Are you sure?
__ 5.In your Virtual I/O Server partition's console session, use the rmdev command to remove the existing SEA, and its associated interface devices. Use the SEA adapter name you wrote down in Step 3.
»If the SEA device is ent3, then run the following command sequence:
$ rmdev -dev ent3
$ rmdev -dev en3
$ rmdev -dev et3
$ entstat -all ent2 | grep VLAN
Invalid VLAN ID Packets: 0
Port VLAN ID: 10
VLAN Tag IDs: None
$ entstat -all ent3 | grep VLAN
Invalid VLAN ID Packets: 0
Port VLAN ID: 19
VLAN Tag IDs: None
__ 11.Use the entstat -all entX | grep Switch command to check that both virtual Ethernet adapters are using the default virtual switch ID ETHERNET0. If not, do not proceed. Check your VIO server profile configuration.
»Here is an example command and its output, which shows ent2 and ent3 using the switch ID ETHERNET0.
$ entstat -all ent2 | grep Switch
Switch ID: ETHERNET0
$ entstat -all ent3 | grep Switch
Switch ID: ETHERNET0
Run the following command to see the VLAN ID of the virtual Ethernet adapter on your client partition. Here is an example with VLAN 30 on lpar3:
$ entstat -d ent0 | grep "Port VLAN ID"
Port VLAN ID: 30
$ mkvdev -sea ent0 -vadapter ent2 -default ent2 -defaultid 30
-attr ctl_chan=ent3 ha_mode=auto
$ lstcpip -adapters
