Shutting down Virtual I/O Server logical partitions using the HMC

You can shut down Virtual I/O Server logical partitions using the Hardware Management Console (HMC). You can shut down the Virtual I/O Server immediately or delay the shutdown.

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 shut down 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 > Shut Down.
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 shut down a logical partition:
1. In the navigation pane, click the Resources icon .
2. Click All Systems. The All Systems page is displayed.
3. 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.
4. In the work pane, select the partition and click Actions > Shutdown.

Select one of the following options:

Option	Description
Operating System	The HMC issues the Virtual I/O Server shutdown command to shut down 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 command to shut down 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.
Delayed	The logical partition waits a predetermined amount of time to shut down. This allows the logical partition time to end jobs and write data to disks.
Immediate	The logical partition shuts down without any preset delay.

Click OK.
