Completed the cluster update

5.Run the package: cmrunpkg cfspkg1

6.Verify that the modular package of disk group(s) and mount point(s) is running. Also, verify that the file system is mounted:

Parallel Activation of Disk Groups and Parallel Mounting of Mount Points

To enable parallel activation of CVM disk groups and parallel mounting of CFS mount points, you must set the following parameters in the package configuration file:

•cvm_concurrent_dg_operations

Specify the number of concurrent disk groups to be activated in parallel during package startup. The default value is 1. Setting this value to an appropriate number improves performance when the package needs to activate a large number of disk groups, since the disk groups are activated in parallel thus consuming lesser time. For example, if a package uses three disk groups that need to be activated in parallel, you must enter the following in the package configuration file:

cvm_concurrent_dg_operations 3

•cfs_concurrent_mount_unmount_operations

Specify the number of concurrent mount operations to allow during package startup. The default value is 1. Setting this value to an appropriate number improves performance when the package needs to mount a number of mount points in parallel. For example, if a package uses three disk groups on which the file systems need to be mounted in parallel, you must enter the following in the package configuration file:

cfs_concurrent_mount_unmount_operations 3
