2. General Cautions and Notes
2.1 General Cautions
- While an array is being built or cleared, DO NOT remove and
reinsert any drive from that array. Doing so may cause
unpredictable results for any of the controller's arrays.
- While a drive is being cleared, DO NOT try to include it in a
new array. Doing so may cause unpredictable results.
- DO NOT move drives containing an array or volume from one
controller to another while the power is on. Doing so could
cause the loss of the array configuration or data, or both.
Instead, power off both affected controllers, move the drives,
and then restart.
2.2 General Notes
- When displaying information on a physical device, the device,
vendor and model information may be displayed incorrectly.
- During array migration from a RAID 1 or RAID 5 to a RAID 0, if
the original array had a spare drive attached, the resulting
RAID 0 retains the spare drive.
- After using a hot spare to successfully rebuild a redundant
array, information about the hot spare drive may not display
as expected. RAID Storage Manager may continue to display
it as a global hot spare.
--------------------------------------------------------------------
3. Array Level-Specific Notes
3.1 RAID 10 Notes
- Performing a Verify and Verify/Fix on a RAID 10 displays the
same message text in the event log, "Build/Verify started on
second level array of array 'Array_0.'" You may see the message
three times for a Verify, but only once for a Verify/Fix.
- During a migration from a RAID 0 to any redundant array like
RAID 1, 5, or 10, RAID Storage Manager shows the status as
"Degraded Reconfiguring" for a moment, then the status changes
to "Reconfiguring." The "Degraded" status does not appear in the
event log.
--------------------------------------------------------------------
4. Controller-Specific Compatibility Issues
4.1 SATA Controllers
- A Clear operation on an array may have a performance impact
on other processes, such as Build/Verify processes, involving the
same array members. Therefore, Dell recommends that you NOT
attempt any other operations while performing a Clear operation
on a SATA array.
--------------------------------------------------------------------
5. RAID Storage Manager Notes
- You can run RAID Storage Manager under all supported
operating systems.
- The blink LED feature is supported only in SAF-TE enabled
enclosures.
- Performing a Verify and Verify/Fix on a RAID 10 displays the same
message text in the event log, something like, "Build/Verify
started on second level array of array 'Array_0.'" You may see the
message three times for a Verify, but only once for a Verify/Fix.
- Task priority is not retained after rebooting. If you change
a priority to LOW or MEDIUM, and reboot, the controller resets the
priority to the default (HIGH).
- When initializing a new array on a HostRAID controller
(eg, CERC SATA 1.5/2s), you cannot change the task priority to
HIGH. The event log indicates that the priority is changed;
however, it actually remains at its previous setting.
- When an array fails, the array name returns to its default name.
- If the RAID Storage Manager detects a change in your network
connection from connected to disconnected, or vice-versa, you
may see a message that the RAID Storage Manager Agent needs to
be restarted.
To restart the agent under Windows:
1. Go to My Computer->Manage->Services
2. Select RAID Storage Manager Agent
3. Click Restart
To restart the agent under Linux, type:
/etc/init.d/stor_man.sh restart
--------------------------------------------------------------------
6. Operating System-Specific Issues and Notes
6.1 Windows
- Formatting a logical volume using the My Computer function
may result in an incomplete format which would necessitate
a reformat. WORKAROUND: Use Windows Disk Management/Manager.
6.2 Linux
- This release supports the following Linux distributions:
° Red Hat 9.0
° Red Hat Enterprise Linux AS 2.1
° Red Hat Enterprise Linux AS 3 and WS 3
- Before you can install the RAID Storage Manager under Red Hat
Enterprise Linux AS 3 or WS 3, you must install two packages
from Red Hat installation CD:
- compat-libstdc++-7.3-2.96.122.i386.rpm
- compat-libstdc++--devel-7.3-2.96.122.i386.rpm
NOTE: The version string in the file name may be different
from above; be sure to check the version string on
the Red Hat CD.
For example, type:
rpm --install /mnt/compat-libstdc++-7.3-2.96.122.i386.rpm
where mnt is the mount point of the CD-ROM drive.
- Under Red Hat 9 with certain hardware configurations the X11
GUI server sometimes aborts when you log into the RAID Storage
Manager. WORKAROUND: Update the X11 (XFree86) package from Red
Hat web site at https://rhn.redhat.com/errata/RHSA-2004-059.htm;
as an alternative, try a different video card.
