Description
Setting an Alert at the Parent Node
Level
You can set alerts at any of the nodes
in the Tree view. Setting an alert at a
parent node level, such as at a host
level, sets alert for any child nodes. If
you set an alert at a parent node level
and any of the in-band storage array
child nodes have a Needs Upgrade
status, the Alert Disables status icon
appears next to the parent node in the
tree view.
Adding a Storage Array
The Contacting Storage Array icon is
shown in the Tree view and Table
view until the current status of each
managed storage array is known.
The Contacting Storage Array icon is
shown in the EMW Status Bar and the
AMW Status Bar and the tooltip
shows Contacting Storage arrays.
As each storage array is contacted,
its current status is obtained and
shown in the Tree view and Table
view. The applicable statuses are the
Optimal, Needs Attention, Fixing, or
Unresponsive.
Adding a Storage Array OK
No problems were encountered while
adding the storage array.
The MD Storage Manager continues
to check for any status change
events.
Adding a Storage Array Error
Displayed only when an error occurs.
In the Tree view, icons can appear in a string to convey more information. For example, the following string means that
the storage array is optimal, an alert is set for the storage array, and firmware is available for download.
NOTE: The MD Storage Manager may take a few minutes to update a status change to Unresponsive or from
Unresponsive. A status change from or to Unresponsive depends on the network link to the storage array. All other
status change updates faster.
Trace Buffers
Trace information can be saved to a compressed file. The firmware uses the trace buffers to record processing activity,
including exception conditions, that may be useful for debugging. Trace information is stored in the current buffer and
can be moved to the flushed buffer after being retrieved. Because each RAID controller module has its own buffer, there
may be more than one flushed buffer. The trace buffers can be retrieved without interrupting the operation of the
storage array and with minimal effect on performance.
NOTE: Use this option only under the guidance of a Technical Support representative.
