Specifying an Alternate Retrieval Location
StorNext User’s Guide 376
For example:
source-LUN-label-name (the original stripe group name) becomes
source-LUN-label-name.old
destination-LUN-label-name (the new stripe group name) becomes
source-LUN-label-name (the same name as the original stripe group)
5 Only if your system includes a standby FSM: After you run
sndiskmove, rescan the disks on the standby FSM’s host by running
cvadmin -e ‘disks refresh’. You must run cvadmin -e ‘disks refresh’ on
all systems on which you have a configured FSM for the file system
involved in the move.
6 Restart the FSM.
7 Only if your system includes a standby FSM: Restart the standby
FSM.
Specifying an Alternate Retrieval Location
The Alternate Retrieval Location feature applies to situations where file
retrieval fails because the normal file copies cannot be retrieved from the
machine on which StorNext Storage Manger resides. This feature enables
you retrieve a copy of the truncated file from a different machine.
Quantum strongly recommends using the StorNext GUI to enable this
feature. If you choose to use the command line interface instead, you can
use the CP1altnode command to add, modify, or delete alternate retrieval
location information. See the fsaltnode man page for more information.
Also, a new -x argument has been added for fsretrieve, which enables you
to make changes when this feature is enabled. For more information, see
the man page for fsretrieve.
Note: When you run sndiskmove, it could take a considerable
amount of time to copy the data between disks, depending
on disk size and performance.
