512e Physical drive support

HPE Smart Storage Administrator is able to detect and correct performance issues caused by nonoptimal
logical drive alignment for 512e physical drives.
The following scenarios indicate that drive support is needed:
• Multiple logical drives exist in a single array.
• An array consists of one or more 512e physical drives.
• At least one of the logical drives in the array is not aligned on a native block boundary. For current
512e drives, the native block boundary is 4K.
HPE SSA displays a warning indicating that the logical drive is not optimally aligned and that performance
of the logical drive is not optimal. Additionally, if one or more of the following scenarios are met, the array
presents a "Realign Logical Drive" button:
• There is enough free space in the array to move the logical drive to be aligned to the native 4K
boundary.
• The controller can perform the transformation (requires a cache module with a fully charged battery or
capacitor connected).
• The controller does NOT have SmartCache enabled.

Diagnosing array problems

Diagnostic tools
To troubleshoot array problems and generate feedback about arrays, use the following diagnostic tools:
• Event Notification Service
This utility reports array events to the Microsoft Windows system event log and IML. You can obtain
the utility from the SmartStart CD or the Hewlett Packard Enterprise website. When prompted for
product information, enter the server model name.
• HPE Insight Diagnostics
Insight Diagnostics is a tool that displays information about the system hardware configuration and
performs tests on the system and its components, including drives if they are connected to Smart
Array controllers. This utility is available on the Hewlett Packard Enterprise website.
