• You must immediately perform a reboot for reconfig of an nPartition when you have removed an active cell from the nPartition. • You must immediately perform a reboot for reconfig of an nPartition when you have removed a cell from an active nPartition and specified the -B option to the parmodify command. • You do not need to perform a reboot for reconfig of an nPartition when you have removed an inactive cell from an nPartition and did not specify the -B option to the parmodify command. In the cases where you must immediately perform a reboot for reconfig after removing a cell, not doing so will leave the Complex Profile locked and thus will prevent any other changes to the server complex configuration. In these cases, the reboot for reconfig is required to complete the cell assignment changes and permit other changes to occur. Procedure 6-8 Removing Cells from an nPartition (nPartition Commands) From the command line, use the parmodify command to remove cells from an nPartition. You also can use the parstatus command to list current nPartition details such as cell assignments. NOTE: You can remotely perform this task using remote administration options supported by the Enhanced nPartition Commands or Partition Manager Version 2.0. Remote administration is supported by the Partition Manager Tools→Switch Complexes action and by the nPartition command -u... -h... options or -g... -h... options. For details see "Tools for Configuring nPartitions" (page 165). 1. Login to a system with the nPartition commands installed. If using remote administration features to modify an nPartition, you can login to any system with Enhanced nPartition Commands installed. If removing an inactive cell from an nPartition, you can use local management from any nPartition in the complex. For example, you can login to HP-UX running on any nPartition in the same server complex. If removing an active cell from an nPartition and not using remote administration features, you must login to the nPartition from which the cell is to be removed. 2. Issue the parstatus -c#... command to list the current nPartition assignments and status for each cell (-c# where # is the cell number) that you plan to remove from its assigned nPartition. Specify each cell you plan to remove with a separate -c option. For example, to list details on cells 0, 1, and 2, issue the parstatus -c0 -c1 -c2 command. The cells must all be assigned to the same nPartition in order to remove them using a single procedure. Otherwise, if the cells are assigned to different nPartitions, you must perform this procedure separately for each nPartition. 3. Remove the cell from the nPartition to which it is assigned by using the parmodify -p# -d#... command. Specify the nPartition (-p# where # is the nPartition number) and each cell (-d# where # is the cell number) that you want to remove from the nPartition. If you are performing this task using the Enhanced nPartition Commands to remotely administer a server, also specify the -u... -h... options or the -g... -h... options as appropriate. If removing multiple cells from an nPartition, specify each cell with a separate -d# option on the same command line (such as: parmodify -p1 -d0 -d2... to remove cells 0 and 2 from partition number 1).
