About AdvancedDisk shared storage access
With the AdvancedDisk option, you can configure access to your file system
storage by more than one media server.
If you do so, be aware of the following:
■ Each media server must mount the file systems of all the disk volumes within
a disk pool.
■ The mount points must be the same on each media server.
NetBackup does not validate mount points, so you must ensure that the mount
points are the same for each media server. You also must ensure that the mount
points are valid.
■ To obtain a consolidated list of disk volumes, NetBackup queries every media
server. For large sets of servers, queries may affect performance.
■ Disk volume status is monitored on a single media server. Which server
monitors the status can change. Therefore, a change in disk volume availability
on one media server may not be reflected in the disk volume status NetBackup
reports.
To enable AdvancedDisk shared storage access by more than one media server:
upgrade the NetBackup master server and the EMM server to NetBackup 6.5.2 or
later. (Normally, the master server and the EMM server are on the same computer.)
You do not have to upgrade 6.5 media servers. NetBackup 6.5 and later commands
support multiple AdvancedDisk media server access to the storage. You can
configure disk pools by using the NetBackup Administration Console on the master
server or NetBackup commands.
To configure shared access, configure multiple media servers as storage servers.
See “Configuring an AdvancedDisk storage server” on page 26.
About AdvancedDisk preferred or required read
servers
When you configure a storage server, you can specify that you want it to be
preferred or required for restore jobs. You also can specify whether a server should
be required for the read side of duplication jobs. These attributes can help manage
the restore and the duplication traffic.
