NetBackup / 5240 Appliance disk drive configuration

NetBackup 5240 Appliance contains 12 SAS hard disk drives. 

The appliance uses the disk drive that is located in slot 11 as a hot-spare disk. 

If one of the disk drives fails in slots 4 through 10, the appliance automatically initiates a RAID 6 rebuild operation. It rebuilds the RAID 6 array by using the hot-spare disk drive in slot 11. 

After you replace the failed disk drive, the appliance then copies the information from the disk drive in slot 11 to the new replacement disk. 

When the copy operation finishes, the disk drive in slot 11 again becomes the hot-spare disk.

robocopy

robocopy <Source> <Destination> [<File>[ ...]] [<Options>]

example:

robocopy Source Destination /E /COPY:DATSOU /R:10 /W:3 /ZB /NP /TEE /LOG+:D:\FileCopy01.log

/e                 Copies subdirectories. Note that this option includes empty directories.

/copyall       Copies all file information (equivalent to /copy:DATSOU).

/r:<N>         Specifies the number of retries on failed copies. 

/w:<N>       Specifies the wait time between retries, in seconds.

/zb               Uses restartable mode. If access is denied, this option uses Backup mode.

/np               Specifies that the progress of the copying operation.

/tee              Writes the status output to the console window, as well as to the log file.
