Downloading disk drive firmware
You might be instructed in K2 release notes to upgrade disk drive firmware. This allows you to take
advantage of the disk drive enhancements and benefit from improved performance and reliability.
To determine your disk drive type and current firmware version, select a disk drive icon in the
Storage Utility tree view, then note the drive properties reported in the right-hand pane. Use the
following procedure if you need to download disk drive firmware.
NOTE: The disk drives are upgraded one at a time which can take as long as 2 minutes per drive.
Take this into consideration when scheduling the upgrade.
1. Refer to K2 Release Notes to determine firmware types, versions, files, and any other special
instructions regarding the particular disk drive firmware you are downloading.
2. In the Storage Utility, right-click a disk in the tree view, then select Advanced | Download Disk
Firmware in the context menu.
3. If online, messages appear “…offline mode now?” and “…continue?”. Click Yes to put the
system in offline mode.
AppCenter channels go offline. The Open File dialog box opens.
4. In the Open File dialog box, browse to the latest firmware file for your disks, select the file, and
click OK.
For internal drives, watch the lights on the drive to which you are downloading firmware. The
lights flash as firmware loads. Wait until the lights have completed their flashing pattern. This
can take several minutes.
The Progress Report window appears showing the disk firmware download task and the percentage
completion.
5. Repeat this procedure on each drive.
6. When finished, exit Storage Utility.
7. Put AppCenter channels back online.
8. Restart.
Placing the K2 system into online mode
If the stand-alone K2 system is in offline mode and you have completed your storage system
configuration tasks, you have the following options to return the system to the online mode:
• Exit Storage Utility and bring channels online — If Storage Utility is closed, first open Storage
Utility and then exit Storage Utility. When you exit Storage Utility you are prompted “…back
to online mode?". Click
Yes .
After exiting Storage Utility, if AppCenter is open the channels remain offline. To bring channels
online, if you are running AppCenter on a Control Point PC, select
System | Reconnect . If you
are running AppCenter on a local K2 system, close and reopen AppCenter.
• Restart the K2 system — Restarting automatically resets the system to online mode. When you
log into AppCenter channels connect and come up online.
