Creating performance data collection schedules
IMPORTANT:
• Only one schedule can be created on a selected command device. For better performance, you
can select a maximum of two command devices that belong to different ports.
• A schedule cannot be created for the same XP array through two different hosts.
• HP recommends that you allow one minute per 1,000 LDEVs for the management station to keep
up with the collection. XP Performance Advisor collects performance data on all LDEVs in the array.
The collection is not limited to the number of LDEVs that the host station is mapped to use.
• You can set the collection interval for performance data collection to a minimum of 1 minute or a
maximum of 60 minutes. HP recommends a collection frequency of 5 minutes.
• If you select all the 7 resource types, you should set a minimum frequency of 15 minutes and a
maximum of 60 minutes.
• For viewing and collecting performance data for large number of LDEVs, you should configure
the java heap size settings in both the management station and host system. For more information,
see “Increasing the maximum number of LDEVs” on page 62.
• If multiple SLPRs are configured in an array, select the command device that is associated with
SLPR0. For example, if SLPR0, SLPR1, and SLPR2 are configured, select the command device that
is associated with SLPR0. However, because of security implementations, you cannot access the
configuration information associated with SLPR0 if you select the command device associated with
SLPR1 or SLPR2.
• If configured in an XP array, it is mandatory that you select all the XP Continuous Access Journal,
Snapshot, and XP Thin Provisioning resources from the respective resource type lists.
• HP recommends that you clear the cache on your IE browser before creating a schedule.
To create a performance collection schedule:
1. Click Array View in the left pane.
