This section explains advisory notes for VMware.
Values for CPU Share and Memory Share
If CPU share and memory share for a virtual L-Server have been set to a value of 1,000,000 or greater using the ROR console, when the VM guest is edited from vSphereClient, these values may be forcibly replaced with 1,000,000.
When setting a value greater than 1,000,000, modify the configuration from the ROR console again.
Operating Systems for which Parameters can be Set and the Prerequisites for Performing the Settings
Depending on the server virtualization software used, some restrictions may apply to the operating systems that parameters can be set for and the prerequisites for performing the settings.
For details, refer to the manual of server virtualization software.
Information
Snapshot
The snapshot function provided by server virtualization software records the disk from the last update. Consequently, when a disk failure occurs, the snapshot function becomes unavailable at the same time.
Snapshot can be used as a corrective measure for problems such as the following:
Example
For recovery when a problems occurs with the applied patch
For recovery when a problem occurs when changing operating system parameters
VMware Storage VMotion
The following are advisory notes for when using VMware Storage VMotion.
When disk resources are moved to a newly created datastore which has not yet been detected by Resource Orchestrator, the information of moved disk resources is reflected as follows:
The newly created datastore is detected as a virtual storage resource during regular update.
After being detected as virtual storage resources, the information of moved disk resources is reflected on Resource Orchestrator.
When using VMware vSphere Client, after completing moving of disk resources, the newest datastore status may not be reflected.
When performing update of the datastore, the newest status is displayed.
VMware FT
When an L-Server is linked with a virtual machine on which VMware FT has been configured, the secondary VM host information can be checked using the following method:
Select the target L-Server on the orchestration tree.
In the [Server recovery] on the [Resource Details] tab, VMware FT (Secondary_VM_host_name) is displayed.
Example
VMware FT(host2)
When migration to the secondary VM host occurs, the secondary VM host information will be updated by periodic update.
VMware DPM, VMware DRS
When starting an L-Server using VMware DPM or VMware DRS, if moving an L-Server (VM guest) between VM hosts using VMware DRS, or turning on a VM host using VMware DPM, refer to "When using VMware DRS or VMware DPM" in "E.1.2 Preparations for Servers" in the "Design Guide CE".
