11.4 Setting System Alerts
While most system alerts are generated automatically without any need for user
configuration, there are several types of alerts that you can specifically configure.
Limits relating to Common Provisioning Groups (CPG) can be set by the user when creating
a CPG and can later trigger alerts. For information on setting the growth increment limits,
see 7.2 Common Provisioning Groups on page 7.4. For details about CPG creation
precautions, refer to the InForm OS Concepts Guide.
Limits for virtual volumes capable of allocating space on demand are also user-configurable
and can trigger alerts. For information about on-demand virtual volume space allocation,
refer to the InForm OS Concepts Guide.
The raw space alert is a global threshold that can be set for the storage system in order to
alert administrators when available space on the system falls below a user-specified level.
When the available space on the storage system falls below this user-specified threshold, an
alert is generated.
There are also four default system thresholds which alert you when the available space on
the system falls below 50%, 75%, 85%, and 95% of the total available space on the system.
When the user-defined threshold is set, alerts for system thresholds below the user-defined
threshold are suppressed. The following section describes how to set and change this raw
space alert threshold.
11.4.1 Setting the Raw Space Threshold Alert
To set a raw space alert for a storage system with Nearline type drives, issue the
setsys RawSpaceAlertNL <threshold>
command.
To set a raw space alert for a storage system with Fibre Channel type drives, issue the
setsys RawSpaceAlertFC <threshold> command.
To set a raw space alert for a storage system with Solid State Drives (SSD), issue the
setsys RawSpaceAlertSSD <threshold>
command.
For each command above,
<threshold> is an integer from 100 to 100,000 that represents
the total available space on the system in gigabytes. A value of 0 effectively disables the raw
space alert safety feature. Any alerts for system thresholds below the user-defined thresholds
are suppressed.
