Sun StorageTek Common Array Manager Software Release Notes 39
Snapshot Reserve Space is Insufficient and Fails Resnap
Bug 6523608 –Refreshing a snapshot does not update the filesystem if there is
insufficient reserve space, yet a message displays indicating success. The array’s
event log says the resnap completed successfully.
Workaround –In the snapshot feature of the management software, configure
snapshots to fail if sufficient reserve space is not available. The fail message will
prompt you to increase the reserve space.
Snapshot Volumes do not Support Read-ahead
Bug 6560461 –Although both the base volume and the snapshot reserve volume
support read-ahead, the snapshot volume itself does not support read-ahead. As a
result, the Read-ahead Enabled Option is set to False on the Snapshot Details page.
Volume Segment Size Associated Requires a New Profile with a Variable
Number of Disks when Changed
Bug 6599933 –Changing a volume created with a one segment size to one with a
different segment size requires that you create a new profile with the desired
segment size, create a pool using that profile, and apply the new pool to the volume.
However, if the original profile was created using a fixed number of disks instead of
a variable number of disks, then an error is returned.
Workaround –Adjust the new profile so that the number of disks is variable instead
of fixed.
Volume-Copy not Supported for 2500 Arrays
Sun StorageTek 2500 series does not support volume-copy. Any instances in the user
interface or documentation that imply there is a command or function for this task
are misleading.
Volumes not Created Using Fractional Sizes
Bug 6665635 –Creating volumes with sizes that contain a fraction does not work in
locales using a comma as decimal point. The check for a legal numeric value is not
localized, but the interpretation of the number afterwards is. If you correctly enter
the locale with a comma as 17,352, you will get this error message: “You must
provide a numeric capacity value.”
