Power Save Technology is not supported on configured drives - IBM ServeRAID
RETAIN tip: H202773
When the Power Save Technology is enabled on Configured Drives on an IBM ServeRAID M controller, the user may see one of the following Events logged inside MegaRAID Storage Manager (MSM) or in ServeRAID M controller firmware logs:
Additionally, when the Power Save Technology is enabled, the user may notice that the "Other Error Count: XYZ" may be increasing in the "MegaCli -LdPdInfo -aALL" log when the drives are transitioning between power states.
Note: More details on the Logical Sense Codes related to the Events listed above:
The system may be any of the following IBM servers:
The system is configured with one or more of the following IBM Options:
This tip is not software specific.
The ServeRAID firmware for the ServeRAID M series controllers is affected.
This behavior has been corrected in updated ServeRAID firmware as follows:
The referenced file is available from the "Support matrix - SAS/SATA II (ServeRAID-MR10i, MR10ie, MR10il, MR10is, MR10k, MR10M, M5014, M5015, and M5025)" at the following URL:
You can manually identify and disable Power Save Settings when running an older ServeRAID firmware version. See the Details section for affected code releases. The changes are dynamic and will take effect soon after completion of the command execution. System reboot is not required. The available tools which can help to accomplish this are:
Make sure that all available drives are unchecked from using Power Savings Technology. Otherwise, uncheck all drives and save the configuration.
Note: Access to the Powersave "Settings" option using the WebBIOS method has been disabled in the latest ServeRAID firmware release.
MSM GUI method
Make sure that all available drives are unchecked from using Power Savings Technology.
To check Power Savings Policy used by the SAS/SATA Controller, use the following MegaCLI commands.
Note: You can enter MegaCLI commands for a single controller (-aN), multiple controllers (-a0,1,2) or work on all present controllers (-aALL). This is denoted as -aN|-a0,1,2|-aALL in this document and specifies that you can enter commands for one controller, multiple controllers, or all controllers.
To check the Power Savings Policy set for Unconfigured and Hot Spare Drives, use the following MegaCLI commands respectively:
To change the Power Savings Policy set for Unconfigured and Hot Spare Drives, use the following MegaCLI commands respectively:
If using ServeRAID adapter firmware version 20.10.1-0036 (M1000 series) or 12.12.0-0047 (M5000 series), check and change the Power Savings Policy from "Automatic" to "None" on the configured drives using the following MegaCLI commands respectively:
Note: MegaCLI version 8.00.48 or greater must be used in order to have the complete ability to modify Power Save Settings.
M10xx - SAS/SATA Controllers
Power Save Technology was first introduced in firmware 20.1.1-0059.
In firmware 20.10.1-0052, the user can enable or disable the Power Save Functions for Unconfigured and Hot Spare Drives. The Power Save Function is turned off for Configured Drives. This means that the user cannot enable Power Savings for these drives. By default the Power Savings are enabled for Unconfigured Drives, but disabled for Hot Spare Drives.
M50xx SAS/SATA Controllers
Power Save Technology was first introduced in firmware 12.7.0-0020.
In firmware 12.12.0-0056, the user can enable or disable the Power Save Functions for Unconfigured and Hot Spare Drives. The Power Save Function is turned off for Configured Drives. (this means that the user cannot enable Power Savings for these drives).
In firmware 12.12.0-0065, the user can enable or disable the Power Save Functions for Unconfigured drives only. The Power Save Function is turned off for Hot Spare and Configured Drives. This means that the user cannot enable Power Savings for these drives. Applications (Command Line Interface (CLI), MSM, etc.) will return "unsupported" error responses if users attempt to access or change the settings for Hot Spare and Configured Drives.
Note: In firmware 12.12.0-0065/20.10.1-0052, the firmware logs may display some Power Saving entries, but these are informational messages and the user can safely ignore those entries.
