VMwareDisks agent
The VMwareDisks agent enables vMotion and VMware Distributed Resource Scheduler (DRS) in InfoScale clusters that are configured and deployed on VMware virtual machines.
When a VCS cluster with a shared disk is configured on virtual machines, VMware does not support VMware Distributed Resource Scheduler (DRS) and vMotion. Thus the vMotion and DRS capabilities are compromised. The solution to this issue is to attach the disks to a single virtual machine at a time in a VCS cluster. In case of a user-initiated failover or a fault-induced failover, these disks fail over (detach-attach) to the target virtual machine along with the service group. The VMwareDisks agent manages the detach and attach operations.
To ensure proper functioning of the VMwareDisks agent, verify the following settings:
If you change the disk naming scheme from an enclosure-based naming scheme (for example,
r7515-xxx-yyy_vmdk0_0
) to a operating system-native naming scheme, then you must set thedisk.EnableUUID=TRUE
attribute in the VMware virtual machine's properties.Set the
disk.EnableUUID=TRUE
attribute in the virtual machine's properties and confirm that the disk's UUID is visible in the vxdisk -px LIST_DMP list command output. The agent scans the disks and checks for the disk UUID in the vxdisk -px LIST_DMP list output. If disk UUIDs are absent, the agent may fail to bring the resource online and get faulted.The VMware disks are in the persistent mode. If the disks are in the independent mode, the agent reverts them to the persistent mode in case of a failover.
The ESX/ESXi host or vCenter user has administrative privileges or is a root user. If you do not want to use the administrator account or the root user, create a role with the privileges that are required to perform operations on the VMwareDisks resource. Then, assign this role to one or more users.
The role assigned to the user account must have the following privileges at a minimum:
Low level file operations
Add existing disk
Change resource
Remove disk
In case of configurations with disks that are part of snapshots, the privileges to remove user-initiated snapshots or to view and manage NetBackup jobs are also required. Beyond these privileges, you can provide additional ones according to the needs of your configuration.
In case of a vCenter user, you must assign the requisite privileges for the user to access the datastore.
To assign vCenter roles and privileges
- Log on to the vCenter Server and navigate to Home > Inventory > Datastores and Datastore Clusters.
- From the vCenter inventory tree view, right-click the appropriate datacenter, and select Add Permission.
Alternatively, open the Permissions tab. On the Permissions pane, right-click and select Add Permission.
- In the Assign Permissions window, add the user, select the role, and assign privileges.
For details, refer to VMware vSphere ESXi and vCenter Server Documentation.
