• If "Deactivate" operation, "Reactivate" operation or logical server
movement operation is performed to the target LPAR during guest
memory dump, the operation takes precedence and the guest memory
data is not retained. Therefore, guest memory dump can no longer be
continued and the guest memory dump is cancelled. When guest memory
dump is in progress, do not perform "Deactivate" operation, "Reactivate"
operation or logical server movement operation to the target LPAR.
• LPARs other than the target LPAR continue to work after guest memory
dump is started, but those that use the LPAR manager management NIC
as shared NIC may be affected as its network performance degrades.
• If Force Recovery is performed on the System Service State screen of the
LPAR manager screen during guest memory dump, the memory dump
operation is cancelled.
• If Update System Config is performed with the F10 key on the System
Configuration screen of the LPAR manager screen during guest memory
dump, the memory dump operation is cancelled.
• If the processing to automatically stop all logical Processors of the target
LPAR fails at the beginning of guest memory dump, the memory dump
operation is cancelled and the target LPAR is deactivated forcibly. If this
deactivation fails, the target LPAR is blocked. When this state occurs,
contact the maintenance personnel.
• If an unrecoverable error occurs during guest memory dump in the LPAR
manager machine that performs guest memory dump, the memory dump
operation is cancelled. When this state occurs, contact the maintenance
personnel.
• If an LPAR manager Assist error occurs during guest memory dump, the
memory dump operation may be cancelled. When this state occurs,
contact the maintenance personnel.
• If a communication error occurs in the network between LPAR manager
machine and external FTP server during guest memory dump, the
memory dump operation is cancelled. When this state occurs, check the
network configuration between LPAR manager machine and external FTP
server. If the problem is still not solved, check whether the FTP software
program of the external FTP server is running correctly. If the problem
still remains, contact the reseller from which you purchased this
equipment or consult maintenance personnel.
• When guest memory dump processing and guest OS dump processing by
the Dump operation on the Front Panel screen are performed
simultaneously to one LPAR, all the logical Processors of the LPAR stop
due to guest memory dump and the guest OS processing stops
accordingly. Therefore, the guest OS dump operation on the Front Panel
screen is disabled, but the guest memory dump is enabled. Remove this
precaution with the following operational procedure:
When you find an abnormal operation of the guest OS and dump the
¢
guest memory data, perform guest OS dump first by the Dump
operation on the Front Panel screen.
If this guest OS dump operation fails, perform the guest memory
¢
dump using the guest memory dump function.
