Restarting VIO Server Logical Partition

Before the admin shutdown VIO server LPAR, admin must remember the following points:

1. If client LPAR uses storage and networking virtual resources provided by VIO server then admin must deactivate the LPAR and then shutdown the client LPAR.
2. Each shared memory partition must be a shutdown because every partition accesses its paging space device using VIO server LPAR that the admin is planning to shutdown.

To restart VIO server from HMC:

1. Expand system management -> servers
2. Click managed systems on which LPAR is located
3. Select LPAR
4. Click Operations -> Restart
5. Click OK

And now complete the following task:

1. Activate client LPAR
2. Activate each shared memory partition that accesses paging space device using VIO server LPAR that is restarted.

P.S: Please refer the redhat IBM pdfs for detailed understanding!

Happy Learning!
