This section explains advisory notes for RHEL5-Xen.
Required Software
When using RHEL5-Xen, Systemwalker Software Configuration Manager is required.
Admin Server
When using RHEL5-Xen as managed servers, the only supported OS of the admin server is Linux.
Managed servers
When using RHEL5-Xen as managed servers, the only server type available for use as managed servers is RHEL5-Xen.
L-Server OS
When using RHEL5-Xen as managed servers, the only OS supported for the L-Server is Linux.
Snapshot
When using RHEL5-Xen, snapshots cannot be used.
Collect L-Server snapshots using PRIMECLUSTER GDS.
The part of the virtual storage name before "-" is the PRIMECLUSTER GDS class name, and the part after "-" is the single disk name.
The disk resource name corresponds to the volume name.
For details on snapshots, refer to the PRIMECLUSTER GDS manual.
VM Type View
In the ROR console, the VM type of VM host and VM guest for RHEL5-Xen is displayed as "Xen".
Shared Disk View
On the ROR console, when multiple L-Servers have shared disk resources, only the information of one L-Server to which the resources are allocated is displayed.
Check the disk shared information, using the rcxadm disk show command.
Max. Number of Possible L-Servers View
The available space on resources and the space displayed for [the number of L-Servers that can be created] are calculated as follows:
Available Amount of CPUs and [Number of L-Servers that can be Created]
Total resource space * 80% - (Total of resources used for L-Server) |
Attaching Resources
When attaching VM hosts, virtual storage or networks, perform the same procedure as in "8.4.2 Registering Resources with Resource Orchestrator" or "8.4.3 Registering Resources in Resource Pools".
Hardware Maintenance
When server failure is detected on Systemwalker Software Configuration Manager, open the ROR console, and identify the failed server. For details on server hardware replacement, refer to "Chapter 9 Hardware Maintenance" in the "Operation Guide CE".
Directory for collecting performance information
When registering resources, create the directories and files on the server where the resources are registered that are necessary for performance monitoring.
Refer to "8.6.9 Advisory Notes for RHEL-KVM Usage" for details.
