Adding virtual adapters dynamically
You can dynamically add a virtual adapter to a running logical partition using the Hardware Management Console (HMC).
A Linux logical partition supports the dynamic addition of virtual adapters only if the DynamicRM tool package is installed on the Linux logical partition. To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems Web site.
To dynamically add a virtual adapter to a running logical partition using the HMC, you must be a super administrator, service representative, product engineer, or operator of the HMC.
If you plan to add a virtual adapter to a logical
partition that uses shared memory (hereafter referred to as a shared
memory partition), you might need to adjust the amount of I/O
entitled memory assigned to the shared memory partition before you
add the adapter.
- If the I/O entitled memory mode of the shared memory partition is set to the auto mode, then you do not need to take action. When you add the new virtual adapter, the HMC automatically increases the I/O entitled memory of the shared memory partition to accommodate the new virtual adapter.
- If the I/O entitled memory mode of the shared memory partition is set to the manual mode, then you must increase the I/O entitled memory that is assigned to the shared memory partition to accommodate the new adapter. For instructions, see Adding and removing I/O entitled memory dynamically to and from a shared memory partition.
To dynamically add a virtual adapter to a running logical
partition, follow these steps:
If you created a virtual fibre channel adapter
on a Virtual I/O Server logical
partition, configure the virtual fibre channel adapter to a physical
port on the physical fibre channel adapter that is connected to the
physical storage that you want the associated client logical partition
to access. For instructions, see Assigning the virtual fibre channel
adapter to a physical fibre channel adapter.
