Operating Systems Solaris Sharing a physical disk with an LDOM Post 303042253 by hicksd8 on Thursday 19th of December 2019 04:16:14 PM
Old 12-19-2019
One thing for sure is that only one of the nodes (Solaris 11 Global or Solaris 10 LDOM) can have control of the volume. In any situation, having two operating systems writing to a volume simultaneously is a recipe for instant filesystem corruption. One operating system must control file opening, locking, etc. Even in a cluster scenario using dual tailed storage, a major function of the cluster suite is to control which node has exclusive control of the volume and effect disciplined failover when necessary.

Therefore, like any two nodes, one option is to mount the volume on one node, configure a NFS share on that node, and mount the volume using a NFS client from the second node. The first node then controls ALL activity on the volume.

NAME
lvremove - remove one or more logical volumes from LVM volume group SYNOPSIS
autobackup] lv_path ... Remarks If the logical volume input arguments belong to a combination of volume groups version 1.0 and 2.0 or higher, the arguments may not be pro- cessed in the order they are listed on the command line. DESCRIPTION
The command removes each logical volume specified by lv_path .... Logical volumes must be closed before they can be removed. For example, if the logical volume contains a file system, the file system before removing it. Options and Arguments recognizes the following options and arguments: lv_path The block device path name of a logical volume. Set automatic backup for this invocation of this command. autobackup can have one of the following values: Automatically back up configuration changes made to the logical volume. This is the default. After this command executes, the command (see vgcfgbackup(1M)) is executed for the volume group to which the logical volume belongs. Do not back up configuration changes this time. Specify that no user confirmation is required. Shared Volume Group Considerations For volume group version 1.0 and 2.0, cannot be used if the volume group is activated in shared mode. For volume groups version 2.1 (or higher), can be performed when activated in either shared, exclusive, or standalone mode. Note that the daemon must be running on all the nodes sharing a volume group activated in shared mode. See lvmpud(1M). When is issued, it removes the logical volume device special files from all the nodes sharing the volume group. When a node wants to share the volume group, the user must first execute a if logical volumes were removed at the time the volume group was not activated on that node. LVM shared mode is currently only available in Serviceguard clusters. EXTERNAL INFLUENCES
Environment Variables determines the language in which messages are displayed. If is not specified or is null, it defaults to "C" (see lang(5)). If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)). EXAMPLES
