Chapter 7 Installing the Nearline Storage System
f. Close the Progress Report and repeat these steps for other unbound disks. If
specified by your system design, you can bind some disks as Hot Spares, as
explained in
“Binding Hot Spare drives” on page 369 . When you are done, if
you did not bind any extra Hot Spares, you should have the following results:
For nearline storage, on the primary RAID chassis you should have two RAID
1 LUNs of two disks each and one Hot Spare Disk. The remainder of the disks
(in one or more Expansion chassis) should be bound as RAID 6 LUNs, with six
disks to a LUN. If have an even number of Expansion chassis (either two chassis
or four chassis), you should have five RAID 6 LUNs across every two chassis.
If you have an uneven number of chassis, you will have three drives left over
that do not fit in one the six drive LUNs. You can bind these extra drives as Hot
Spares if desired.
NOTE: Controllers can take several hours to bind a LUN. Make sure you initiate
multiple simultaneous binding processes to reduce the overall time.
g. Upon 100% completion, click Close in Progress Report window.
NOTE: Do not proceed until all LUNs are finished binding.
4. Restart the K2 Media Server.
NOTE: Make sure start up processes on the K2 Media Server are complete before
proceeding. This could take ten minutes.
5. Continue with the next procedure “Creating a new file system” .
