HP P6000 HP Controller Enclosure Cache DIMM Replacement Instructions (593091-0 - Page 2

Verifying component failure Use the following methods to verify component failure: • Analyze any failure messages received. HP Insight Remote Support Software provides a recommended fault monitoring solution. • Check status using HP P6000 Command View: 1. In the navigation pane, select Storage system > Hardware > Controller enclosure and then select a controller. 2. The status is displayed in the Memory section and the Condition/State section. The status in the Memory section could show a memory amount inconsistent with the amount known to be installed. The Cache state in the Condition/State section could show an operational state of (Failed) to indicate a fault that may require a replacement. 3. To help identify the correct controller, click Locate > Locate On. This causes the blue UID indicator to light on the controller module at the rear of the controller enclosure. • Check the controller status LEDs as shown in Figure 2 and Table 1. Item LED 4 MEZZ 5 6 Indication Applicable to the P6300/P6500 EVA only. Amber LED indicates the iSCSI or iSCSI/FCoE module status that is communicated to the array controller. Slow flashing amber LED indicates an IP address conflict on the management port. Solid amber indicates an iSCSI or iSCSI/FCoE module critical error or shutdown. Green LED indicates write-back cache status. Slow flashing green LED indicates standby power. Solid green LED indicates cache is good with normal AC power applied. Amber LED indicates DIMM status. The LED is off when DIMM status is good. Slow flashing amber indicates DIMMs are being powered by battery (during AC power loss). Solid amber indicates a DIMM failure. Figure 2 Controller status LEDs . Table 1 Controller status LEDs Item LED Indication Blue LED used to identifies a specific con- troller module within the enclosure or the 1 iSCSI or iSCSI/FCoE module (P6300/P6500 EVA only) within the con- troller. Green LED indicates controller health. LED 2 flashes green during boot and becomes solid green after boot. Flashing amber indicates a controller termin- ation or the system is inoperative and atten- tion is required. Solid amber indicates that 3 the controller cannot reboot and should be replaced. If both the solid amber and solid blue LEDs are lit, the controller has com- pleted a warm removal procedure, and can be safely swapped. Removing a DIMM module CAUTION: Verify the location of the controller being serviced. Removing the wrong controller can result in data loss. 1. Halt I/O to the controller with HP P6000 Command View: a. In the navigation pane, select Storage System > Hardware > Controller Enclosure. b. Select the appropriate controller (Controller 1 or Controller 2) to halt. c. Click the Shut down tab. d. In the Halt Controller section of the Shut Down Controller window, click Halt. This halts controller processing while the power remains on. 2. Disconnect the Fibre Channel and/or SAS (if applicable) cables from the halted controller. Ensure they are marked to facilitate reconnecting later. Page 2
