AVAILABILITY



This command is part of Veritas Storage Foundation for DB2.
To determine whether this product is installed on an \1 system, type:




lslpp -L VRTSdb2ed







DESCRIPTION



The db2ed_ckptmount command is used to mount a Storage Checkpoint into the file system namespace. A mounted Storage Checkpoint appears as any other file system on the machine and can be accessed using all normal file system-based commands.





OPTIONS



The following options are supported:





-I DB2INSTANCE 





Specifies the name of the DB2 instance. If the instance name is not specified, the current user will be used as the instance owner.





-D DB2DATABASE 





Specifies the name of the DB2 database whose Storage Checkpoint will be mounted.





-c CKPT_NAME   





Specifies the name of the Storage Checkpoint to be mounted. This Storage Checkpoint must have been created using the db2ed_ckptcreate or db2ed_ckptcreate command.





-m MOUNT_POINT  





Specifies the mountpoint where the Storage Checkpoint will be mounted.  If the specified mountpoint does not exist, then db2ed_ckptmount creates it before mounting the Storage Checkpoint, as long as the current instance owner has permission to create it.





-o ro | rw





Specifies read-only or read-write for mounting the Storage Checkpoint. By default, all read-only Storage Checkpoints are mounted as read-only. Mounting a read-only Storage Checkpoint as read-write requires creating a shadow Storage Checkpoint of the existing read-only one to ensure that the original read-only Storage Checkpoint is preserved. Thus, the mounted Storage Checkpoint name will be different than the one named on the command line if the rw option is used. \_wrxxx, where xxx is an integer, will be appended to the Storage Checkpoint name if it is mounted as read-write.
All read-write Storage Checkpoints will always be mounted as read-write.





-h





Shows command usage.









EXAMPLES



This example shows how to mount a Storage Checkpoint with the read-write option:





$ /opt/VRTS/bin/db2ed_ckptmount -D PROD -c Checkpoint_971672042 -m /tmp/ckpt_rw -o rw

Creating Storage Checkpoint on /tmp/ckpt_rw/udb_home/udb01a_home 
with name Checkpoint_971672042_wr001








This example shows how to mount a Storage Checkpoint with the read-only option:





$ /opt/VRTS/bin/db2ed_ckptmount -D PROD -c Checkpoint_971672042 -m /tmp/ckpt_ro -o ro













NOTES



db2ed_ckptmount can be run as either the DB2 instance owner or the superuser.
