Chapter 14 Administering and maintaining the K2 Storage System
❑
From the control point PC, open
the K2 System Configuration
application and launch Storage
Utility.
“Accessing Storage Utility” on
page 514 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 first of a series of
informational screens opens.
3. Work through the
informational screens .
4. The expansion process runs.
A dialog box displays
progress.
The expansion process runs.
A dialog box displays
progress.
5. Wait for the process to
complete. On a large system
this can take over 30 minutes.
6. A “…succeeded…” message
is displayed when done. Click
OK and Storage Utility closes.
7. 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.
When prompted to retry, if you are not sure
if the process started, you can retry to be
sure. Doing so does not cause problems.
Make sure Storage Utility is closed before
proceeding.
❑
If directed, modify RTIOS. Do this step only under the direction
of Grass Valley Support. As
directed, use a text editor to modify
the SNFS configuration file on K2
Media Servers (both primary and
backup) with the role of media file
system/database server.
NOTE: Don’t use the
SNFS configuration tool
to modify the system
configuration. Doing so
causes unexpected
changes in the
configuration file,
resulting in a failure of the
expansion process.
Depending on your use of the expanded file
system, you might need to change the
RTIOS value. This value can be calculated
only by Grass Valley Support.
❑
Restart all K2 Media
Servers.
Refer to the start up procedure in the
installation chapter for your level of
K2 Storage System. Make sure to
first start servers with the role of
media file system/database server
and, if a redundant K2 Storage
System, manually start Failover
Monitor. When the server that takes the role of FTP
server starts, one of the following happens:
• If you answered “Yes” to restripe
existing media in the step above, the
Restripe Utility automatically
launches and begins restriping
media.
• If you answered “No” to restripe
existing media in the step above, the
Restripe Utility does not launch.
