Verifying If RDR Disks Are Resynchronizing
When you complete or abort the Active Upgrade process, the system reestablishes the mirrors
between the RDR partner disks in each CPU- I
⁄
O enclosure. If you intend to initiate another
upgrade process, you must wait for the resynchronization to complete before you do so.
You can tell if a disk is resynching by viewing the LEDs on the front panel of the disk. For
information about interpreting the LEDs, see “Disk Operations Using the RDR (Rapid Disk Resync)
Function” in Chapter 3, “Windows Setup and Operation.”
You can also view the status of your disks using one of the following methods:
•
Run a readiness check. On the Active Upgrade page, click Retry. If the disks are still
resynching, the upgrade state will be reported as
Fault Tolerant\Idle\Broken and the activity
log will display errors indicating that the disks are not ready.
•
Verify the disks on the Disk Selection page. Any volume that is in red is simplexed (and thus,
probably still resynching). When a disk volume is only green, it is duplxed and you can start
another upgrade.
For more about the disk status on the
Disk Selection page , see “Selecting Disks to Upgrade”
on 5-116.
To view the status of an RDR virtual disk in RDR Utility
1. On RDR Utility, click Logical Disk Information .
2. Click one of the RDR Virtual Disk items (RDR Virtual Disk x).
3. Check the value of the Status property, which displays Resync nn% ( where nn is the
percentage completed) while the disk is resynchronizing. When the resync process is finished,
the value is
None .
Ensure that the value of the Status property for all RDR Virtual Disks is None before you retry the
Active Upgrade process.
