4.4.1 Preparation for IOU hot add

The description of the flow of preparations is given below.
1. Arrange for the IOU for addition.
2. Check if number of IOU required for addition is available.
3. Insert the IOU to be added into a free IOU slot.
This step is performed by the field engineer in charge of your system.
4. Mount cables other than LAN cables if you also add PCI Express card.
This step is performed by the field engineer in charge of your system.
Note
- If you add an IOU with PCI Express cards, insert PCI Express cards into the IOU before inserting the IOU
into the slot.
For how to confirm the slot number of the PCI Express slot, see 'Confirming the slot number of a PCI
Express slot' in
- Check if the I/O device is normally operating in the free partition. During addition, I/O pre-diagnostic
process is not executed.

4.4.2 DR operation of IOU hot add

This section describes the DR operation for IOU hot add.
1. Log into the MMB Web-UI using Administrator privileges.
2. Execute the hotadd command.
Example：When adding IOU1 in partition1.
Administrator > hotadd partition 1 IOU 1
Are you sure to continue adding IOU#1 to Partition#1? [Y/N]
Y
DR operation start (1/3)
Assigning IOU#1 to partition#1 (2/3)

Administrator >
3. Perform "show dynamic_reconfiguration status" command and confirm below messages.
Example: When adding IOU1 to partition 1.
"Adding IOU#1 to Partition#1, completed." or "not executed."
4. Execute /opt/FJSVdr-util/sbin/dr stat IOU command in the operating system shell.
The list of IOUs connected to the system is displayed. Check if the IOU that was added is displayed.
Example： When IOU1 is added.
# /opt/FJSVdr-util/sbin/dr stat IOU
IOU0: online
IOU1: offline
IOU2: empty
IOU3: empty
When newly adding an IOU to a partition, it will be displayed as offline since the IOU is not recognized by
the operating system.
5. Execute /opt/FJSVdr-util/sbin/dr add IOU1 command in the operating system shell.
The IOU that was newly added to the partition will be powered on.
Example：When IOU1 is powered on
# /opt/FJSVdr-util/sbin/dr add IOU1
