3 Features Topics: • • • • • • • Controller features Virtual disk features Hard drive features Fault tolerance Operating system device enumeration Controller mode Non-RAID disk Controller features This section lists the following controller features supported on PowerEdge RAID Controller (PERC) 10 cards in detail: ● 1 MB I/O ● Auto Configure RAID 0 ● Disk roaming ● FastPath ● H745P MX enclosure support ● Non-RAID disk ● Physical disk power management ● PERC H840 enclosure support ● Profile Management ● Se
Using disk roaming Perform the following steps to use disk roaming: 1. Turn off the power to the system, physical disks, enclosures, and system components. 2. Disconnect power cables from the system. 3. Move the physical disks to desired positions on the backplane or the enclosure. 4. Perform a safety check. Make sure the physical disks are inserted properly. 5. Turn on the system. The controller detects the RAID configuration from the configuration data on the physical disks.
Figure 9. Multipath topology for the MX7000 modular system In this illustration, the H745P MX resides in the compute sled and functions as an interface to the SAS topology of the MX7000. The H745P MX is used to configure drives that are located in the MX5016s storage sled into RAID volumes. The H745P MX connects to a pair of MX5000s SAS I/O modules (IOMs) that manage connections between the compute and storage sleds in the MX7000. For more information about configuring drive assignments, see the www.dell.
Physical disk power management Physical disk power management is a power-saving feature of PERC 10 series cards. The feature allows disks to be spun down based on disk configuration and I/O activity. The feature is supported on all rotating SAS and SATA disks, and includes unconfigured and hot-spare disks. The physical disk power management feature is disabled by default.
1. To connect a single enclosure, cable the ports so that the enclosure is connected to both the ports on the controller card. 2. To connect multiple enclosures, connect two cables from the controller to the first enclosure as in case in point no 1. Next, connect cables from the first enclosure to the second enclosure. From here, continue to connect two cables from the last enclosure in the chain to the next enclosure you wish to include until you have up to 4 enclosures connected. Figure 11.
Setting up redundant path support on the PERC H840 adapter The PERC H840 card can detect and use redundant paths to disks contained in enclosures. With redundant paths to the same device, if one path fails, another path can be used to communicate between the controller and the device. To connect single enclosure, cable the ports so that the enclosure is connected to both the ports on the controller card. See Figure 6.
● ● ● ● ● ● ● Single virtual disk performance or latency in hypervisor configurations Virtual disk write cache policy Virtual disk read cache policy Virtual disk migration Virtual disk Initialization Reconfiguration of virtual disk Background operations Virtual disk write cache policies The write cache policy of a virtual disk determines how the controller handles writes to the virtual disk. Table 3.
Table 4. Read policies (continued) Feature Description Adaptive read ahead Adaptive read ahead is no longer supported. Selecting adaptive read ahead is equivalent to selecting the read ahead option. Virtual disk migration The PERC 10 series supports migration of virtual disks from one controller to another without taking the target controller offline. The controller can import RAID virtual disks in optimal, degraded, or partially degraded states. You cannot import a virtual disk that is offline.
Fast initialization A fast initialization on a virtual disk overwrites the first and last 8 MB of the virtual disk, clearing any boot records or partition information. The operation takes only 2–3 seconds to complete, but it is followed by BGI, which takes a longer time to complete. To perform a fast initialization using the HII Configuration Utility, see Configuring virtual disk parameters. NOTE: During full or fast initialization, the host cannot access the virtual disk.
See the following table for a list of RLM or OCE options: The source RAID level column indicates the virtual disk RAID level before the RLM or OCE operation and the target RAID level column indicates the RAID level after the RLM or OCE operation. Table 5. RAID level migration Source RAID Level Target RAID Level Number of Physical Number of Disks (Beginning) Physical Disks (End) Capacity Expansio n Possible Description RAID 0 RAID 0 1 or more 2 or more Yes Increases capacity by adding disks.
Background operations Background initialization Background initialization (BGI) is an automated process that writes parity or mirror data on newly created virtual disks. BGI does not run on RAID 0 virtual disks. You can control the BGI rate in the Dell OpenManage storage management application. Any change to the BGI rate does not take effect until the next BGI is executed. NOTE: ● On PERC H345, background operations will not run until the operating system boots. ● You cannot disable BGI permanently.
Instant secure erase Instant secure erase (ISE) drives use the same encryption technology as SED drives but do not allow the encryption key to be secured. The encryption technology allows the drive to be re-purposed and securely erased using the cryptographic erase function. NOTE: ISE drives do not provide protection against theft. 4 KB sector disk drives PERC 10 controllers support 4 KB sector disk drives, which enables you to efficiently use the storage space.
NOTE: To enable automatic replace member, use the Dell OpenManage storage management application. Patrol Read The Patrol read feature is designed as a preventative measure to ensure physical disk health and data integrity. Patrol read scans and resolves potential problems on configured physical disks. The Dell OpenManage storage management application can be used to start patrol read and change its behavior.

Drive state/operation (continued) Drive state/operation Unconfigured slot Slot configured in VD Insert configured locked drive into the system (unlockable) Foreign Cryptographic Erase (If configured VD is not secured) ● Rebuild or copyback start ● Original drive data lost Insert locked drive into the system (non-unlockable) Foreign locked Foreign locked Physical disk hot swapping NOTE: To check if the backplane supports hot swapping, see your system owner's manual.
Controller cache preservation The controller is capable of preserving its cache in the event of a system power outage or improper system shutdown. The PERC 10 series controller is attached to a battery backup unit (BBU) that provides backup power during system power loss to preserve the controller's cache data. Cache preservation with non-volatile cache The non-volatile cache (NVC) allows controller cache data to be stored indefinitely.
The order for H740P, H745, H745P MX, H840 is: 1. Non-RAID disks are enumerated first based on slot ID. 2. Virtual disks are enumerated second based on virtual disk target ID. NOTE: If a virtual disk target ID occupies the slot ID, a non-RAID disk may not display in the slot order. NOTE: OS enumeration may not be in this order if virtual disks or non-RAID disks are created while the operating system is running.
Controller operating mode Enhanced HBA mode (H740, H745, H745P MX) RAID mode (H740, H745) RAID mode (H745P MX, H840) RAID mode (H345) Write back-caching Yes (VDs only) Yes Yes No Key management support (see Security key and RAID management) LKM SEKM and LKM LKM No Patrol read Yes (VDs only) Yes Yes Yes (VDs only) reset, and when unconfigured disks are hot-inserted.

9 Troubleshooting To get help with your Dell PowerEdge RAID Controller (PERC) 10 series, you can contact your Dell Technical Service representative or see https://www.dell.com/support.
Corrective Action: Contact Dell Technical Support. BIOS disabled error message Error Message: BIOS Disabled. No Logical Drives Handled by BIOS. Probable Cause: This warning message is displayed after you disable the ROM option in the configuration utility. When the ROM option is disabled, the BIOS cannot boot to Int 13h and cannot provide the ability to boot from the virtual disk.
Discovery error message Error Message: A discovery error has occurred, please power cycle the system and all the enclosures attached to this system. Probable Cause: This message indicates that discovery did not complete within 120 seconds. The SAS cables for your system might be improperly connected. Corrective Action: Check the cable connections and fix any problems. Restart the system.
Foreign configuration found error message Error Message: Foreign configuration(s) found on adapter. Press any key to continue, or ’C’ to load the configuration utility or ’F’ to import foreign configuration(s) and continue. Probable Cause: When a controller firmware detects a physical disk with existing foreign metadata, it flags the physical disk as foreign and generates an alert indicating that a foreign disk was detected.
Preserved Cache State The controller preserves the dirty cache from a virtual disk if the virtual disk goes offline or is deleted because of missing physical disks. This preserved dirty cache is called pinned cache and is preserved until you import the virtual disk or discard the cache. 1. Import the virtual disk—Power off the system, re-insert the virtual disk and restore the system power. Use the HII Configuration Utility to import the foreign configuration. 2.
General issues PERC card has yellow bang in device manager Issue: The device is displayed in Device Manager but has a yellow bang (exclamation mark). Corrective Action: Reinstall the driver. For more information on reinstalling drivers, see Driver installation. PERC card not seen in device manager Issue: The device does not appear in the Device Manager. Corrective Action: Turn off the system and reseat the controller. For more information, see Deploying the PERC card.
Multiple disks are inaccessible Issue: Multiple disks are simultaneously inaccessible. Probable Cause: Multiple physical disk errors in a single array typically indicate a failure in cabling or connection and could involve the loss of data. Corrective Action: You can recover the virtual disk after multiple physical disks become simultaneously inaccessible. Perform the following steps to recover the virtual disk: CAUTION: Follow the safety precautions to prevent electrostatic discharge. 1. 2. 3. 4. 5.
Redundant virtual disk fails during reconstruction Issue: Multiple disks fails during a reconstruction process on a redundant virtual disk that has a hot spare. Probable Cause: Multiple physical disks in the virtual disk is failed or the cables are disconnected. Corrective Action: No action is required. The physical disk to which a reconstruction operation is targeted reverts to Ready state, and the virtual disk goes to Failed state.
Smart error detected on a physical disk in a non-redundant virtual disk Issue: A SMART error is detected on a physical disk in a non-redundant virtual disk. Corrective Action: Perform the following steps: 1. Back up your data. 2. Use Replace Member or set up a global hot spare to replace the disk automatically. NOTE: For more information about the Replace Member feature, see the topic Configuring hot spare. 3. Replace the affected physical disk with a new physical disk of equal or higher capacity. 4.
Linux operating system errors Virtual disk policy is assumed as write-through error message Error: kernel: sdb: asking for cache data failed kernel: sdb: assuming drive cache: write through Corrective Action: The error message is displayed when the Linux Small Computer System Interface (SCSI) mid-layer asks for physical disk cache settings.
If the drive is in the Advanced Host Controller Interface (AHCI) mode, the status LED indicator does not power on. Drive status indicator behavior is managed by Storage Spaces Direct. Not all drive status indicators may be used. Table 17.
10 Appendix RAID description RAID is a group of independent physical disks that provides high performance by increasing the number of disks used for saving and accessing data. CAUTION: In the event of a physical disk failure, a RAID 0 virtual disk fails, resulting in data loss. A RAID disk subsystem offers the following benefits: ● Improved I/O performance and data availability. ● Improved data throughput because several disks are accessed simultaneously.
NOTE: The maximum number of virtual disks is currently limited to 192, because of the supported enclosure configuration. RAID 10 configuration In PERC 10 and PERC 11 controllers, RAID 10 can be configured without spanning up to 32 drives. Any RAID 10 volume that has more than 32 drives require spanning. Each span can contain up to 32 drives. Drives must be distributed evenly across all the spans with each span containing an even number of drives.

Spanned RAID levels Spanning is a term used to describe the way in which RAID levels 10, 50, and 60 are constructed from multiple sets of basic, or simple RAID levels. For example, a RAID 10 has multiple sets of RAID 1 arrays where each RAID 1 set is considered a span. Data is then striped (RAID 0) across the RAID 1 spans to create a RAID 10 virtual disk. Similarly, RAID 50 and RAID 60 combine multiple sets of RAID 5 or RAID 6 respectively with striping.
