You receive the following error: HSCL3656
There is an insufficient amount of memory available on the destination
managed system for the configuration of the partition. Please perform
one or both of the following actions: 1. Remove memory from any shutdown
dedicated memory partitions on the destination managed system. 2.
Remove memory from any running dedicated memory partitions on the
destination managed system.
|
- To make physical memory available for the mobile
partition, dynamically remove physical memory from inactive logical
partitions that use dedicated memory (subsequently
referred to as dedicated memory partitions) on the
destination server by running the chhwres command
from the HMC command
line. For example, chhwres -r mem -m <destination_server> -o
r -p <logical_partition> -q <memory>,
where:
- <destination_server> is the name of the
server to which you want to move the mobile partition.
- <logical_partition> is the name of the logical
partition from which you want to remove physical memory.
- <memory> is the amount of physical memory,
in MB, that you want to remove from the logical partition.
- If you cannot satisfy the memory requirement of
the mobile partition by removing physical memory from dedicated memory partitions that are inactive,
dynamically remove physical memory from dedicated
memory partitions that are active on the destination server by
performing one of the following tasks:
|
You receive the following error: HSCL03EC
There is not enough memory: Obtained : xxxx, Required : xxxx.
Check that there is enough memory available to activate the partition.
If not, create a new profile or modify the existing profile with the
available resources, then activate the partition. If the partition
must be activated with these resources, de-activate any running partition(s)
using the resource then activate this partition.

memory partitions that are active on the destination server by
performing one of the following tasks:
- If you cannot satisfy the memory requirement of the
mobile partition by dynamically removing physical memory from dedicated
memory partitions that are active on the destination server, dynamically
remove memory from the mobile partition. For instructions, see Removing dedicated memory
dynamically using the HMC.
- If you cannot reduce the amount of memory required by the mobile
partition to an amount that is equal to or less than the amount of
memory that is available on the destination server, shut down logical
partitions on the destination server until enough memory is available
for the mobile partition to activate on the destination server.
- If you cannot satisfy the memory requirement of the mobile partition
by shutting down logical partitions on the destination server, move
the mobile partition to the destination server by using inactive partition mobility.
|
|
Notes: - The mobile partition must use dedicated memory. If the mobile
partition uses shared memory, skip step 3 and continue to the
next step.
- After you move the logical partition to the destination server,
you might be able to dynamically add one logical memory block (LMB)
back to the logical partition. This can happen in one or more of the
following situations:
- The actual available LMBs on the destination server are fractionally
high. When determining the available LMBs on the destination server,
all fractional LMB sizes are rounded down to the nearest whole number.
For example, 5.9 LMBs are rounded down to 5 LMBs.
- The amount of internal hypervisor storage used on the destination
server (to support the logical partition) is a small fraction of 1
LMB. When determining the amount of memory required by the logical
partition on the destination server, one LMB is added to the actual
number of LMBs required by the logical partition. The added LMB accounts
for internal hypervisor storage required to support the logical partition
on the destination server.

You receive the following error: HSCLA319
The migrating partition's virtual Fibre Channel client adapter cannot
be hosted by the existing Virtual I/O Server (VIOS) partitions on the
destination managed system.
|
This error indicates that the VIOSs in the target server
do not have suitable resources to host the virtual Fibre Channel adapter
on the migrating or suspended partition.
The following are the most common reasons for this error:- The storage area network (SAN) employs port zoning. The target
server ports and source server ports are not zoned identically. To
host the migrating virtual adapter, the list of Fibre Channel targets
in a port on the target server must exactly match the list of Fibre
Channel targets in the current mapped port of the migrating virtual
adapter on the source server.
- The two worldwide port names (WWPNs) assigned to the virtual adapter
are not zoned identically. The two WWPNs must be interchangeable from
both SAN and storage point of view.
- The target server does not have a port that can meet or exceed
the maximum transfer size of the source server port. The maximum transfer
size is an attribute of the Fibre Channel port and can be viewed by
running the lsattr command on a Fibre Channel device.
- A switch on the SAN might be configured to use features that extend
the Fibre Channel standard in ways that are not compatible with Live Partition Mobility. For
example, a port binding feature that tracks WWPN-to-port mappings.
This feature can cause problems because Live Partition Mobility validation
requires that all ports must be explored through a series of login
and logout operations. If the switch tries to track the WWPN-to-port
mappings, it might run out of resources and not permit login operations.
Disabling this type of feature solves some problems related to failed
Fibre Channel login operations.

If the operating system running in the mobile
partition does not explicitly support the processor version register
of the destination server, and the processor determines that explicit
support is required, the processor will not allow the migration to
proceed. |
Perform one of the following actions:- Move the logical partition to another system.
- Update the operating system to a level that supports the target
system processor version registers.
|
You receive an error pertaining to the operating
system when you attempt to migrate a logical partition. |
- Examine the operating system error logs for operating system-related
failures.
- Examine the HMC log
for application-related failures.
|
You receive an HMC error pertaining to
insufficient physical memory on the destination
server. Important: Sufficient physical memory
includes the amount of available physical memory
on the server and the amount of available contiguous physical memory
on the server. If the mobile partition requires more contiguous physical memory, making more physical memory
available will not solve the problem.
|
Perform one
of the following actions:
|
The HMC (or HMCs) and managed system
lost their connection while the migration was in progress, or the
migration failed. |
Before running migration recovery ensure
that the Resource Monitoring and Control (RMC) connections are established
for the migrating partition and the VIOS partitions on the
source and destination servers. Complete the following steps
from the HMC that
manages the source server. If the source server or the source HMC are unavailable, complete
the following steps from the HMC that
manages the destination server.- In the navigation pane, open Systems Management.
- Select Servers.
- In the work pane, select the source server. If the source server
is unavailable, select the destination server.
- In the Tasks menu, select . The Migration Recovery
window is displayed.
- Click Recover.
- If you recovered the migration from the HMC that manages the destination
server (and a different HMC manages
the source server), you might have to manually perform additional
recovery tasks on the source server to finish the recovery. For example,
even though the migration occurs and the mobile partition runs on
the destination server, the mobile partition might appear as an inactive
logical partition on the source server. In this situation, remove
the mobile partition from the source server to finish the recovery.
Tip: You can also run the migrlpar -o r command
to recover a migration.
Note: When you migrate a partition
remotely, ensure that you do not connect the source and target servers
to the same HMC.
|
While attempting to change resources dynamically,
you receive an error that the RMC daemon is not connected. |
This error typically occurs when there is
a network connection problem between the logical partitions and the HMC. To resolve this error,
check your system network setup.

Live Partition Mobility fails
when the client logical partition has multiple virtual Fibre Channel
adapters mapped to the same physical Fibre Channel adapter. |
You cannot migrate or suspend logical partitions
that have multiple virtual Fibre Channel adapters mapped to the same
physical Fibre Channel adapter. |
