Sun StorageTek Availability Suite Properties
The following table describes the Sun StorageTek Availability Suite properties that the
Geographic Edition software defines.
Table A-1 Sun StorageTek Availability Suite Properties
|
|
Device Group Property: Enable_volume_set (Boolean) |
Defines whether the volume sets
and fallback snapshots that are defined in the /var/cluster/geo/avs/AVSdevicegroupname-volset.ini and the /var/cluster/geo/avs/AVSdevicegroupname-snapshot.ini
files are enabled by the Oracle Solaris Cluster Geographic Edition software when the
device group is added to a protection group. Set to either true or
false. Tuning recommendations: This property cannot be tuned after the device group is
added to a protection group. Category: Optional Default: false |
Device Group Property: Local_logical_host (string) |
Defines
the local logical hostname that is used for the replication of the device
group. Do not use an underscore ( _) character in the logical hostname. Tuning recommendations:
This property cannot be tuned after the device group is added to a
protection group. Category: Required Default: None |
Data Replication Property: Nodelist (string array) |
Lists the host
names of the machines that can be primary for the device group in
the protection group. Device groups in the protection group must share the same
ordered node list. This list is comma delimited. Tuning recommendations: This property
can be tuned only when the protection group is offline. Category: Optional Default: All nodes
in the cluster |
Data Replication Property: Remote_logical_host (string) |
Defines the remote logical hostname that
is used for the replication of the device group. Do not use an
underscore ( _) character in the logical hostname. Tuning recommendations: This property cannot be
tuned after the device group is added to a protection group. Category: Required Default: None
|
Replication Resource Property: Snapshot_volume (string array) |
Defines all fallback snapshots automatically enabled by Oracle
Solaris Cluster Geographic Edition 3.2 11/09 software for the secondary volumes in a
single device group. A fallback snapshot is a compact dependent shadow volume
created on the secondary cluster immediately prior to the resynchronization of a secondary
volume, from which the secondary volume can be reconstructed if resynchronization fails.
This Snapshot_volume property is set on the Sun StorageTek Availability Suite replication resource
AVSdevicegroupname-rep-rs that is automatically created for a device group when it is added
to a protection group. The value of the property is an array
containing multiple entries: one for every volume in the device group for which
a fallback snapshot is configured. Entries are in the form master_vol:shadow_vol:bitmap_shadow_vol where
master_vol specifies one replicated volume in the device group for which a
fallback snapshot is enabled, shadow_vol specifies a shadow volume, and bitmap_shadow_vol specifies the
bitmap volume for the shadow volume. Full path names are required and all
three volumes must be in the same device group. Tuning recommendations: This
property can be tuned any time. Category: Optional Default: None |
