Resetting the operating system on a partition

Restart the operating system when an operating system in a logical partition hangs.

The HMC enables the operating system on a logical partition to be reset when errors are encountered in the operating system. The system can undergo either a soft or hard reset.

To reset the operating system, you must be a member of one of the following roles:

super administrator
service representative

Note: For i5/OS® logical partitions, use this task only if you cannot restart the i5/OS logical partition from the command line of the operating system. Using this window to restart an i5/OS logical partition will result in an abnormal IPL.

To reset the operating system on a logical partition, complete the following steps:

In the Navigation Area, expand Server and Partition.
Click Server Management.
In the Contents area, select the logical partition that is running the operating system that you want to reset.
In the menu, click Selected > Restart partition.
Select the type of operating system restart.
Click Yes.
