Specifying an Alternate Retrieval Location

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)

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.

Restart the FSM.

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. 

When you run sndiskmove, it could take a considerable 

amount of time to copy the data between disks, depending 

on disk size and performance.
