Connection to the group or member might have been lost, or a Smart Copy made from a clustered environment may be unreachable. Usually these Smart Copies are not listed under the Unreachable node, but as a regular Smart Copy with an unreachable icon instead of the normal volume or application icon. Find out why ASM/ME cannot reach the group and correct the problem, or wait until the connection is reestablished automatically. Troubleshooting Broken Smart Copies A Smart Copy is broken when ASM/ME cannot validate the Smart Copy because: • Part of the set is missing (such as a missing snapshot) • No more snapshot reserve is available for a volume • The group deleted the oldest snapshot (Smart Copy) of a volume per its snapshot space recovery settings Delete the broken Smart Copies and create new ones immediately to maintain your service level. See Smart Copy Validation for more information about validating Smart Copies. Troubleshoot Recoverable Smart Copies A Smart Copy is listed under the Recoverable node if the cloned volume from which it was created was deleted on the PS Series group. These Smart Copies can be recovered if the cloned volume is restored (undeleted) on the group. See Smart Copy Properties for Volumes for more information. View Smart Copy Details You can view Smart Copy details in ASM/ME. For example, you can see whether a specific Smart Copy is a clone, replica, or snapshot, and whether the Smart Copy is mounted or not, as follows: 1. Expand the Smart Copies node in the tree panel. 2. Navigate to the specific Smart Copy for which you want to view details. Select the Smart Copy in the tree panel, and its properties are displayed. You can view individual snapshots and cloned volumes on the PS Series group where they reside. You can view replicas from either the primary or the secondary group. Smart Copy Validation A Smart Copy contains a backup document residing on the computer, describing one or more Smart Copies stored on a PS Series group. Under certain circumstances, the Smart Copy object stored on the group might become temporarily or permanently disconnected from the computer. For example: • If the PS Series group runs out of snapshot space, a Smart Copy might be deleted. • If a scheduled keep count is exceeded, an older Smart Copy might be deleted. Under such circumstances, the backup document on the computer becomes unusable. 52 General ASM/ME Operations

Troubleshooting Unreachable Smart Copies
A Smart Copy is considered unreachable when ASM/ME cannot reach a PS Series group during the validation process. Connection to the
group or member might have been lost, or a Smart Copy made from a clustered environment may be unreachable. Usually these Smart
Copies are not listed under the Unreachable node, but as a regular Smart Copy with an unreachable icon instead of the normal volume or
application icon.
Find out why ASM/ME cannot reach the group and correct the problem, or wait until the connection is reestablished automatically.
Troubleshooting Broken Smart Copies
A Smart Copy is broken when ASM/ME cannot validate the Smart Copy because:
•
Part of the set is missing (such as a missing snapshot)
•
No more snapshot reserve is available for a volume
•
The group deleted the oldest snapshot (Smart Copy) of a volume per its snapshot space recovery settings
Delete the broken Smart Copies and create new ones immediately to maintain your service level.
See
Smart Copy Validation
for more information about validating Smart Copies.
Troubleshoot Recoverable Smart Copies
A Smart Copy is listed under the Recoverable node if the cloned volume from which it was created was deleted on the PS Series group.
These Smart Copies can be recovered if the cloned volume is restored (undeleted) on the group. See
Smart Copy Properties for Volumes
for more information.
View Smart Copy Details
You can view Smart Copy details in ASM/ME. For example, you can see whether a specific Smart Copy is a clone, replica, or snapshot,
and whether the Smart Copy is mounted or not, as follows:
1.
Expand the
Smart Copies
node in the tree panel.
2.
Navigate to the specific Smart Copy for which you want to view details. Select the Smart Copy in the tree panel, and its properties are
displayed.
You can view individual snapshots and cloned volumes on the PS Series group where they reside. You can view replicas from either the
primary or the secondary group.
Smart Copy Validation
A Smart Copy contains a backup document residing on the computer, describing one or more Smart Copies stored on a PS Series group.
Under certain circumstances, the Smart Copy object stored on the group might become temporarily or permanently disconnected from
the computer. For example:
•
If the PS Series group runs out of snapshot space, a Smart Copy might be deleted.
•
If a scheduled keep count is exceeded, an older Smart Copy might be deleted.
Under such circumstances, the backup document on the computer becomes unusable.
