Also, the name cannot be the same as any device-ID name.ĭual-string mediators – Each disk set configured with exactly two disk strings and mastered by exactly two Solaris hosts must have Solaris Volume Manager mediatorsĬonfigured for the disk set. Local volume names – The name of each local Solaris Volume Manager volume on which a global-devices file system, nodeid, is mounted must be unique throughout the cluster. Guidelines for Solaris Volume Manager SoftwareĬonsider the following points when you plan Solaris Volume Manager configurations: See your volume-manager documentation for disk layout recommendations and any additional restrictions. Hot-spare disks – You can use hot-spare disks to increase availability, but hot spare disks are not required. However, configured VxVM disk groups do not have an association

Solaris Volume Manager software can automatically check for this connection at the time that devices are added to a disk set. Used to construct a device group to all of the nodes that are configured in the node list for that device group. Multihost disks – You must connect, or port, all devices that are See the resource group planning information in the Sun Cluster Data Services Planning and Administration Guide for Solaris OS for information about node lists. Or, if a scalable resource group uses more nodes than its associated device group, make the scalable resource group's node list a superset of the device group's node list. Node lists – To ensure high availability of a device group, make its node lists of potential masters and its failback policy identical to any associated If so, the name of each local volume on which a nodeid file system is to be mounted must be unique throughout the cluster. Unique naming – You might have local Solaris Volume Manager or VxVM volumes that are used as devices on which the nodeid file systems are mounted. See Mirroring Guidelines for guidelines about deciding whether to mirror the root disk. Mirrored root – Mirroring the root disk ensures high availability, but such mirroring is not required. Use software mirroring if the storage device provides hardware RAID as well as redundant paths to devices. See Guidelines for Mirroring Multihost Disks for guidelines on mirroring multihost disks. Mirrored multihost disks – You must mirror all multihost disks across disk expansion units. Software RAID – Sun Cluster software does not support software RAID Guidelines for Volume-Manager SoftwareĬonsider the following general guidelines when you configure your disks with volume-manager software:

See your volume-manager documentation and Configuring Solaris Volume Manager Software or Installing and Configuring VxVM Software for instructions about how to install and configure the volume-manager software.įor more information about the use of volume management in a cluster configuration, see Multihost Devices in Sun Cluster Concepts Guide for Solaris OS and Device Groups in Sun Cluster Concepts Guide for Solaris OS. If you install both volume managers on the same voting node, you must use Solaris Volume Manager software to manage disks that are local to each node.

You are only required to install and license VxVM on those voting nodes that are attached to storage devices that VxVM manages. You must install and license VxVM with the cluster feature on all voting nodes of the cluster. You must install Solaris Volume Manager software on all voting nodes of the cluster, regardless of whether you use VxVM on some nodes to manage disks. Table 1–4 Supported Use of Volume Managers With Sun Cluster Software Sun Cluster software supports Solaris Volume Manager software and Veritas Volume Manager (VxVM) software that you install or use in the following ways. Sun Cluster software uses volume-manager software to group disks into device groups which can then be administered as one unit. Guidelines for Veritas Volume Manager Software

Guidelines for Solaris Volume Manager Software This section provides the following guidelines for planning volume management of your cluster configuration: For Solaris Volume Manager, also add this planning information to the Volumes Worksheet (Solaris Volume Manager). Add this planning information to the Device Group Configurations Worksheet and the Volume-Manager Configurations Worksheet.
