Edit a Frozen I/O Domain

Language:

Starting with the SuperCluster Q3.2021 update patch (branch number 3.2.0.2036 or later of the assistant), you can edit an I/O Domain while it is frozen. This enables you to increase or decrease the amount of CPU and memory resources before you thaw the I/O Domain. Decreasing resources is necessary if the previous amount of resources are no longer available.

For information about identifying your version of SuperCluster software, see Check the SuperCluster Virtual Assistant Version.

Note - You cannot edit the number of zones while the I/O Domain is frozen. To edit the number of zones, the I/O Domain must be active on the system.

Use this procedure to edit a frozen I/O Domain.

See Log In to the SuperCluster Virtual Assistant.
In the navigation panel, select I/O Domains.
Select the frozen I/O Domain.
Click Edit.

At the bottom of the page, select the number of cores and memory.
Click Alter Reservation.
When the I/O Domain is thawed, it will have the resources that you selected.
