  • -WT (Write through), WB (Write back): Selects write policy.

  • -DskCache: Displays drive cache policy.
  • -PSPolicy: Displays the default and current power savings policy of the virtual drive.
  • -Consistency: Displays if the physical drive is consistent or not.

BGI rate:

A controller property indicating the rate at which the background initialization of virtual drives will be carried out.

copyback

The procedure used to copy data from a source drive of a virtual drive to a destination drive that is not a part of the virtual drive.

The copyback operation is often used to create or restore a specific physical configuration for a drive group

(for example, a specific arrangement of drive group members on the device I/O buses).

The copyback operation can be run automatically or manually.

Typically, a drive fails or is expected to fail, and the data is rebuilt on a hot spare. The failed drive is replaced with a new drive.

Then the data is copied from the hot spare to the new drive, and the hot spare reverts from a rebuild drive to its original hot spare status.

The copyback operation runs as a background activity, and the virtual drive is still available online to the host.

A drive property indicating the capacity to which a drive has been coerced (forced) to make it compatible with other drives that are nominally the same capacity. For example, a 4-GB drive from one manufacturer might be 4,196 MB, and a 4-GB from another manufacturer might be 4,128 MB. These drives could be coerced to a usable capacity of 4,088 MB each for use in a drive group in a storage configuration.

Foreign Configuration Disk Re-add to RAID & Rebuild

 

<1> Make the drive online again:

MegaCli64 -PDMakeGood -PhysDrv[32:2] -a0

* The controller will now recognise the disk as being a "foreign" one.

(It means it has detected some RAID informations on it)

<2>

MegaCli64 -CfgForeign -Import -a0

Remark: Import Fail

The MegaRAID Utility may display a “Failed to Import Foreign Configuration” error.

There are two ways the error may occur:

In a server system, if the HDDs are offline and the system is power cycled, the RAID configuration will be removed.

If the user selects for the HDDs to come back online, they can import the original RAID configuration.

If the user chooses to import an individual RAID configuration (for example, “Configuration 1” or “Configuration 2”), the import will fail.

如果是更新了新 RAID Card, 那可能是新不支援舊

Prepare Unconfigured Drives for Removal

Remove a non-failed drive that is connected to the controller

=> Firmware spins down this drive.

=> The drive state is set to Unaffiliated, which marks it as offline even though it is not a part of a configuration.

# -Undo: This option undoes this operation. If you select undo, firmware marks this drive as Unconfigured Good.

MegaCli64 -PDPrpRmv [-Undo] -PhysDrv[E:S] -a0

i.e.

MegaCli64 -PDPrpRmv -PhysDrv[252:0] -a0

Prepare for removal Success

--------

Unconfigured(bad)

Drives stuck in the Unconfigured(bad) state need to be manually set back to Unconfigured(good) before they will be importable.

Failure to import arrays usually means that the drives were unexpectedly powered off or disconnected from the RAID controller,

which puts them in the Unconfigured(bad) state.

原因:

This is done as a precautionary measure to prevent drives with bad connections from joining the array,

as sudden disconnects can result in data corruption.

-Rx[E0:S0,...]

Specifies the RAID level and the drive enclosure/slot numbers to construct a drive group.

-strpszM

Specifies the stripe size, where the stripe size values are

8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256 KB, 512 KB, or 1024 KB.

-Hsp[E5:S5,...]

Creates hot spares when you create the configuration.

Default: WT, NORA

IO Policy (Direct|Cached)

Direct(default):

In Direct I/O mode, reads are not buffered in cache memory.

Data is transferred to the cache and the host concurrently.

If the same data block is read again, it comes from cache memory.

Cached:

In Cached I/O mode, all reads are buffered in cache memory.

Drive Cache: Specify the drive cache policy.

Enable: Enable the drive cache.

Disable(default): Disable the drive cache.

i.e.

MegaCli64 -cfgldadd R1[252:0,252:1] WB RA -a0

Step3: 查看建立出來的 VD Info.

MegaCli64 -LDInfo -LAll -a0 | less

Adapter 0 -- Virtual Drive Information:
Virtual Drive: 1 (Target Id: 1)
Name                :
RAID Level          : Primary-1, Secondary-0, RAID Level Qualifier-0
Size                : 465.25 GB
Is VD emulated      : No
Mirror Data         : 465.25 GB
State               : Optimal
Strip Size          : 64 KB
Number Of Drives    : 2
Span Depth          : 1
Default Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Default Access Policy: Read/Write
Current Access Policy: Read/Write
Disk Cache Policy   : Disabled
Ongoing Progresses:
  Background Initialization: Completed 0%, Taken 0 min.
Encryption Type     : None
Bad Blocks Exist: No
Is VD Cached: No

Step4: 設定(-LDSetProp)

MegaCli -LDSetProp {-Name LdNamestring} | -RW|RO|Blocked|RemoveBlocked |
WT|WB|ForcedWB [-Immediate] |RA|NORA| Cached|Direct |
-EnDskCache|DisDskCache | CachedBadBBU|NoCachedBadBBU |-LN -aN

Allows you to change the following virtual drive parameters:

Write policy: WT (Write through), WB (Write back)

  • Read policy NORA (No read ahead), RA (Read ahead)
  • Selects cache policy: -Cached, -Direct:
  • Specifies whether to use write cache when the BBU is bad: -CachedBadBBU | NoCachedBadBBU
  • Access policy: -RW, -RO, Blocked
  • Drive cache: -EnDskCache | -DisDskCache

i.e.

# Rename

MegaCli64 -LDSetProp -NAME R1 -L1 -a0

Set name to R1 on Adapter 0, VD 1 (target id: 1) success

# Cache

MegaCli64 -LDSetProp WB -L1 -a0

MegaCli64 -LDSetProp RA -L1 -a0

Set BGI Rate

MegaCli64 -AdpSetProp BgiRate -100 -a 0

Adapter 0: Set BGI Rate to 100% success.

MegaCli64 -AdpGetProp BgiRate -a0

Adapter 0: BGI Rate = 100%

Remove Virtual Drive

 * 此 CMD 係沒有 Comfirm 的 !!

MegaCli64 -CfgLdDel -L1 -a0

Adapter 0: Deleted Virtual Drive-1(target id-1)

 


All Disk To RAID0(CfgEachDskRaid0)

Cache Flush is successfully done on adapter 0.

 


IT與 IR Mode

 

IT mode stands for "initiator target".

It presents each drive individually to the host.

IR mode is in whatever raid formats the HBA supports.

Some allow you to present drives individually as JBODs or raid0 with one drive each.
