You can enable the Sun StorEdge Availability Suite 3.2.1 volume sets in one of two ways:
Automatically, when the device group is added to the protection group, avspg
Use the automatic procedures to prepare the devicegroupname-volset.ini file when you are setting up Sun StorEdge Availability Suite 3.2.1 software for the first time. After you have prepared the file, when you add the device group to the protection group, set the Enable_volume_set property of a device group to True. The Sun StorEdge Availability Suite software reads the information in the devicegroupname-volset.ini file to automatically enable the device group.
Manually, after the device group is added to the protection group, avspg
Use the manual procedures to enable the volume sets when you are creating volumes on a system that has been configured.
In this example, the cluster-paris cluster is the primary and avsset is a device group that contains a Solaris Volume Manager diskset.
This example has the following entries in the /var/cluster/geo/avs/avsset-volset.ini file:
logicalhost-paris-1 /dev/md/avsset/rdsk/d100 /dev/md/avsset/rdsk/d101 logicalhost-newyork-1 /dev/md/avsset/rdsk/d100 /dev/md/avsset/rdsk/d101 ip async C avsset |
The avsset-volset.ini file contains the following entries:
lh-paris-1 – Primary host
/dev/md/avsset/rdsk/d100 – Primary data
/dev/md/avsset/rdsk/d101 – Primary bitmap
lh-newyork-1 – Secondary host
/dev/md/avsset/rdsk/d100 – Secondary data
/dev/md/avsset/rdsk/d101 – Secondary bitmap
ip – Protocol
async – Mode
C – C tag
avsset – Diskset
The sample configuration file defines a volume set that replicates d100 from cluster-paris to d100 on cluster-newyork by using the bitmap volumes and logical hostnames that are specified in the file.
In this example, the cluster-paris cluster is the primary and avsdg is a device group that contains a VERITAS Volume Manager disk group.
This example has the following entries in the /var/cluster/geo/avs/avsdg-volset.ini file:
logicalhost-paris-1 /dev/vx/rdsk/avsdg/vol-data-paris \ /dev/vx/rdsk/avsdg/vol-bitmap-paris logicalhost-newyork-1 /dev/vx/rdsk/avsdg/vol-data-newyork \ /dev/vx/rdsk/avsdg/vol-bitmap-ny ip async C avsdg |
The avsdg-volset.ini file contains the following entries:
lh-paris-1 – Primary host
/dev/vx/rdsk/avsdg/vol-data-paris – Primary data
/dev/vx/rdsk/avsdg/vol-bitmap-paris – Primary bitmap
lh-newyork-1 is the secondary host.
/dev/vx/rdsk/avsdg/vol-data-newyork – Secondary data
/dev/vx/rdsk/avsdg/vol-bitmap-ny – Secondary bitmap
ip – Protocol
async – Mode
C – C flag
avsdg – Device group
The sample configuration file defines a volume set that replicates vol-data-paris from cluster-paris to vol-data-newyork on cluster-newyork. The volume set uses the bitmap volumes and logical hostnames that are specified in the file.
In this example, the cluster-paris cluster is the primary and rawdg is the name of the device group that contains a raw device disk group, /dev/did/rdsk/d3.
This example has the following entries in /var/cluster/geo/avs/avsdg-volset.ini file:
logicalhost-paris-1 /dev/did/rdsk/d3s3 /dev/did/rdsk/d3s4 logicalhost-newyork-1 /dev/did/rdsk/d3s5 /dev/did/rdsk/d3s6 ip async C rawdg |
The rawdg-volset.ini file contains the following entries:
logicalhost-paris-1 – Primary host
/dev/did/rdsk/d3s3 – Primary data
/dev/did/rdsk/d3s4 – Primary bitmap
logicalhost-newyork-1 – Secondary host
/dev/did/rdsk/d3s5 – Secondary data
/dev/did/rdsk/d3s6 – Secondary bitmap
ip – Protocol
async – Mode
C – C flag
rawdg – Device group
The sample configuration file defines a volume set that replicates d3s3 from cluster-paris to d3s5 on cluster-newyork. The volume set uses the bitmap volumes and logical hostnames that are specified in the file.
After you have added the device group to the protection group, avspg, you can manually enable the Sun StorEdge Availability Suite 3.2.1 volume sets.
This example manually enables a Solaris Volume Manager volume set.
phys-paris-1# /usr/opt/SUNWesm/sbin/sndradm -e logicalhost-paris-1 \ /dev/md/avsset/rdsk/d100 /dev/md/avsset/rdsk/d101 \ logicalhost-newyork-1 /dev/md/avsset/rdsk/d100 \ /dev/md/avsset/rdsk/d101 ip async C avsset |
This example manually enables a VERITAS Volume Manager volume set.
phys-paris-1# /usr/opt/SUNWesm/sbin/sndradm -e logicalhost-paris-1 /dev/vx/rdsk/avsdg/vol-data-paris /dev/vx/rdsk/avsdg/vol-bitmap-paris logicalhost-newyork-1 /dev/vx/rdsk/avsdg/vol-data-newyork /dev/vx/rdsk/avsdg/vol-bitmap-newyork ip async C avsdg |
This example manually enables a raw device volume set.
phys-paris-1# /usr/opt/SUNWesm/sbin/sndradm -e logicalhost-paris-1 /dev/did/rdsk/d3s3 /dev/did/rdsk/d3s4 logicalhost-newyork-1 /dev/did/rdsk/d3s5 /dev/did/rdsk/d3s6 ip async C dsk/d3 |
Information about the sndradm command execution is written to the Sun StorEdge Availability Suite 3.2.1 log file, /var/opt/SUNWesm/ds.log. Refer to this file if errors occur while manually enabling the volume set.
