5-113container Commandscontainer splitTo split a mirror set or a multilevel array of mirror sets into twoseparate single-partition volume sets or two multilevel arrays ofsingle-partition volume sets, use the container splitcommand. Once this command completes execution, the twovolume sets cannot be merged.Before using this command to split an array, shut down systemapplications (such as, databases) in order to flush application data tothe controller.When you split a mirror set or a multilevel array of mirror sets, thesystem creates a new (referred to as the split) array. The split arraycontains half of the storage data from the original (referred to as themaster) array (mirror set). In addition, the split array has anidentical copy of the data from the old disk at the time of the splitoperation.On Windows NT/Windows 2000 (basic disk only)/Windows XP(basic disk only), the split array’s file system may be inconsistentand you should verify and repair it as follows: Assign a drive letter to the split array using the containerassign drive_letter command. Run the Windows NT/Windows 2000 (basic disk only)/Windows XP (basic disk only) CHKDSK command with the /Fswitch. See your Windows documentation for information onhow to use the CHKDSK command.On UnixWare, before splitting a mirror set that contains a volumetable of contents, run the edvtoc command and change thevolume label to a series of twelve spaces. You can then use thecontainer split command to split the mirror set.Syntaxcontainer split {container}
