Restarting Virtual I/O Server logical partitions using the HMC

You can restart Virtual I/O Server logical partitions using the Hardware Management Console (HMC). Restarting a Virtual I/O Server logical partition shuts down the Virtual I/O Server logical partition and then starts it again.

Before you shut down the Virtual I/O Server logical partition, complete the following tasks:

If the client logical partitions that use storage and networking virtual resources provided by the Virtual I/O Server are not configured to use virtual resources provided by a redundant Virtual I/O Server, then shut down the client logical partitions.
Shut down each shared memory partition that accesses its paging space device using only the Virtual I/O Server logical partition that you plan to shut down. If you shut down the Virtual I/O Server (VIOS) logical partition (hereafter referred to as a paging VIOS partition) before you shut down the shared memory partitions and a shared memory partition attempts to access memory that is located on its paging space device, the shared memory partition might fail.
If a shared memory partition accesses its paging space device redundantly through two paging VIOS partitions, you do not need to shut down the shared memory partition. When you shut down the paging VIOS partition, the shared memory partition accesses its paging space device through the other paging VIOS partition.

To restart a Virtual I/O Server logical partition, complete the following steps from the HMC:

In the navigation pane, expand Systems Management > Servers.
Click the managed system on which the logical partition is located.
In the work pane, select the logical partition.
From the Tasks menu, click Operations > Restart.
The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.
When the HMC is at version 8.7.0, or later, complete the following steps to restart a logical partition:
1. In the navigation pane, click the Resources icon .
2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition. Click View System Partitions. The All Partitions page is displayed.
3. In the work pane, select the logical partition and click Actions > Restart.

Select one of the following options:

Option	Description
Operating System	The HMC issues the Virtual I/O Server shutdown -restart command to shut down and restart the logical partition. This option is available only when the operating system is running, and not when the logical partition is in an Open Firmware state.
Operating System Immediate	The HMC issues the Virtual I/O Server shutdown -force -restart command to shut down and restart the logical partition as quickly as possible, bypassing messages to other users. This option is available only when the operating system is running, and not when the logical partition is in an Open Firmware state.
Immediate	The logical partition is restarted as quickly as possible, without notifying the logical partition.
Dump	The HMC initiates a main storage or system memory dump on the logical partition and restarts the logical partition after the dump.

Click OK.

After the Virtual I/O Server restarts, complete the following tasks:

Activate the client logical partitions that use storage and networking virtual resources provided to them by the Virtual I/O Server.
Activate each shared memory partition that accesses its paging space device by using only the paging VIOS partition that you restarted.
