3.2.4 Taking control over the paired logical volume groups (transfer control from the main site to the remote site)

Using RAID Manager's horctakeover command, take control over the paired logical volume groups in which the update-copy target files are located at the remote site. During this process, the volume attributes at the remote site are set to P-VOL. Use the command to take control over all paired logical volume groups. For details about the horctakeover command, see the RAID Manager documentation.

An example of taking control over paired logical volume groups is shown below. The following system configuration is assumed.

System definition example

 
set pd_system_id = HRD1
set pd_rise_use = Y
set pd_rise_pairvolume_combination = hybrid
set pd_rise_fence_level = data
pdunit -u UNT1 -x host1 -d "/opt/HiRDB_S"
pdstart -t SDS -s sds1 -u UNT1
 

horctakeover command execution example (executed from the remote site)

 
horctakeover -g HRD1_sds1_DB -t 10000
horctakeover -g HRD1_sds1_LOG
horctakeover -g HRD1_UNT1_USTS
horctakeover -g HRD1_sds1_SSTS
horctakeover -g HRD1_sds1_SPD
