Expanding the media file system by bandwidth
❑
Verify versions of controller
microcode and disk firmware.
Update if necessary.
Refer to K2 Storage System Release
Notes and
Make sure that versions are compatible on
both new and existing disks and RAID
storage devices.
❑
Bind RANKs using the new disks.
Wait for the binding process to
complete.
“About full/background bind” on
page 498
Do not unbind or bind existing RANKs.
Doing so destroys all data. If in doubt, flash
drive lights to identify disks.
❑
Close Storage Utility.

❑
Restart the primary K2 Media
Server.
Do not use the standard startup
processes here. Just start up the
server and wait until the Windows
desktop appears. On a redundant K2
Storage System, do not open Server
Control Panel or manually start
Failover Monitor.
Check the Windows Device Manager to
verify that the server “sees” both the old
RANKs and the new RANKs.
❑
Start up all remaining K2 Media
Servers that are connected to the
K2 Storage System.
Do not use the standard startup
processes here. Just start up the
server(s) and wait until the Windows
desktop appears. On a redundant K2
Storage System, do not open Server
Control Panel or manually start
Failover Monitor.

Configure media file system
❑
From the control point PC, open
the K2 System Configuration
application and launch Storage
Utility.
“Accessing Storage Utility” on
page 464
In Storage Utility make sure both old
RANKs and new RANKs are displayed.
❑
Using Storage Utility, expand
the file system by bandwidth.
1. Select
Tools | Expand File
System By Bandwidth
and
answer
Yes
to confirm.
A dialog box opens, asking if you
want to restripe existing media
after bandwidth expansion.
2. Click
Yes
to restripe media,
No
to skip restriping.
The expansion process runs. A
dialog box displays progress.
3. Wait for the process to
complete. On a large system
this can take over 30 minutes.
4. A “…succeeded…” message
is displayed when done. Click
OK
and Storage Utility closes.
5. The K2 System Configuration
application displays a
message informing you to
restart servers. Click
OK
.
When asked about restriping existing
media, the typical response is to click Yes.
In any case this does no harm. Click No
only if you are sure you do not need to
restripe existing media, such as in the
following cases:
•
You have very little existing media
so the fact that it cannot use the new
stripe group does not impact future
media operations or capacity.
•
Your existing media is to be deleted
soon so you don’t care if it uses the
new stripe group.
Make sure Storage Utility is closed before
proceeding.
❑
If Aurora media is present,
modify VolumeConfig.xml.
