This section explains about the settings to be done before restoring the system disk.
When mirroring among servers function is used, perform the following settings regardless of whether the system disk is mirrored by GDS.
[Setting procedure]
When restoring after stopping all the nodes
When all the nodes are started, perform the following settings.
If a node is stopped, the following settings are not necessary.
Execute the following command on any node for all the classes where the netmirror group exists. The latest disk is selected by executing this command.
# /etc/opt/FJSVsdx/bin/sdxnetdisk -S -c class_name |
When restoring in each node one by one
When restoring in one node while the service continues in the operating node and then switching to another operating node to continue the service for restoring in another node, perform the following settings in advance.
Confirm the status of slice which belongs to the netmirror volume.
Execute the following command on any node.
# sdxinfo -S |
If the slice is INVALID, perform the synchronization copying for the netmirror volume.
Execute the following command on any node.
# sdxcopy -B -c class_name -v volume_name |
Wait until the synchronization copying is completed.
The execution status of synchronization copying can be confirmed in the STATUS field of the sdxinfo -S command output. If "COPY" is displayed, the synchronization copying is still in progress.
When the synchronization copying is completed, "ACTIVE" or "STOP" is displayed.
# sdxinfo -S |
