Before the autotake feature became available in the Solaris 9 4/04 release, Solaris Volume Manager did not support the automatic mounting of file systems on disk sets through the /etc/vfstab file. Solaris Volume Manager required the system administrator to manually issue a disk set take command by using the metaset -s setname -t command before the file systems on the disk set could be accessed.
With the autotake feature, you can set a disk set to be automatically accessed at boot time by using the metaset -s setname -A enable command. The autotake feature makes it possible for you to define at boot the mount options for a file system in the /etc/vfstab file. This feature allows you to define the mount options in the /etc/vfstab file for file systems on volumes in the enabled disk set.
Only single-host disk sets support the autotake feature. The autotake feature requires that the disk set is not shared with any other systems. A disk set that is shared cannot be set to use the autotake feature, and the metaset -A command will fail. However, after other hosts are removed from the disk set, it may then be set to autotake. Similarly, an autotake disk set cannot have other hosts added to it. If the autotake feature is disabled, additional hosts can then be added to the disk set.
In a Sun Cluster environment, the autotake feature is disabled. Sun Cluster handles the take and release of a disk set.
For more information on the autotake feature see the -A option of the metaset(1M) command.
