   This command displays the number of drives, RAID level, and so forth for the specified logical drive.

Use the following sequence of commands to set the recommended RAID configuration:

1. Enter CTRL-Y to enter the Preboot CLI when prompted during boot

2. Enter the following Preboot CLI command to clear configuration:

   TRC	Command
   End of Sale UCS C260 M2 TRC1 (Extra-Large TRC)	-cfgclr -l0
   End of Sale UCS C240 M3S TRC1 (Large TRC)	-cfgclr -a0
   End of Sale UCS C240 M3S TRC2 (Medium TRC / BE7000M M3)
   End of Sale UCS C220 M3S TRC1 (Medium TRC)
   End of Sale UCS C220 M3S TRC3 (Small Plus TRC / BE6000H M3)
   End of Sale UCS C220 M3S TRC2 (Small TRC / BE6000M M3)
   End of Sale UCS C210 M2/M1 TRCs (Medium TRC)
   End of Sale UCS C200 M2 TRC1 (Small TRC / BE6000M M2)

To determine the enclosure ID and drive numbering, which is required before you can configure RAID, run the following commands:

The Cisco UCS Rack-Mount Server enclosure ID is not predictable, so you need to substitute the Device ID acquired above for <encl> in the commands below. When all drives are in a single enclosure, the slot numbering starts at zero. This may not be true in all cases, so verify the slot numbering with the following command:

Use the following command to set up RAID on the existing drives on each RAID controller:

Set the Strip Size to 128 KB with the following command-line option on -cfgldadd command lines in step 5 above : -strpsz 128. Also set required Read Policy and Write Policy described above via appropriate command line options. E.g. -cfgldadd -r5 [26:1, 26:2, 26:3, 26:4, 26:5, 26:6, 26:7, 26:8] WB RA Cached NoCachedBadBBU -strpsz 128 -a0.

The following commands are not necessary for new drives that have not been used.

• Use the -ldinit -start -l0 -a0 and –ldinit –start –l1 –a0 commands to perform a fast initialize.
• To clear data on previously used drives and to slow (or full) initialize a new array, use the -ldinit -start -full -l0 -a0 and -ldinit -start -full -l1 -a0 commands. Allow the commands to finish before exiting the Preboot CLI. When both commands, –ldinit –showprog –l0 –a0 and –ldinit –showprog –l1 –a0, show that initialization is not running, it is safe to exit the Preboot CLI.

  Note	We have noticed that a slow initialize can take up to 95 minutes or more to fully complete for array sizes of 1 TB+ that are used in a UCS C240 M3 Rack-Mount Server TRC1 deployment.

After you configure the logical volume, exit the Preboot CLI by entering q.

During the boot process, ensure that Quiet Boot is disabled, and press Ctrl-H at the LSI screen when prompted. The MegaRaid BIOS Configuration utility opens and displays the LSI MegaRAID SAS adapters. Select Adapter 0 to begin and click Start.

Select New Configuration and click Next.

Select Manual Configuration.

On the next screen, you need to add drives to a Drive Group. Select one drive and then select all others by holding down Shift and the Down Arrow key. Click Add to Array.

Click Accept DG.

Add the drive group to a span. Select DG0 and click Add to Span.

After the drive group is part of a span, you can configure RAID on it.

1. Select RAID 5 or RAID 10 from the list of available options.

2. Cisco recommends that you select 128KB from the Strip Size drop-down list.

Set Read Policy to read ahead = always.

Set Write Policy to one of the following:

Click Update Size to finalize the RAID 5 volume and to determine the size of the resulting volume. A warning relating to BBU appears. Click Yes to accept a possible performance degradation if the BBU is over-tasked.

Click Next on the next screen to accept the Virtual Drive you just created (VD 0).

Click Next. At the next screen, you are presented with the option to initialize the array. Click:

1. Fast Initialize

2. Go

3. Set Boot Drive

4. Go

The RAID configuration is now complete for the first RAID controller. Go back to the controller selection by clicking on Controller selection. This time, select Adapter 1.

Repeat all the steps that you performed for Adapter 0 with this new Adapter to set up the second RAID 5 array.

At the LSI screen, press CTRL-R.

Under Virtual Drive Management screen, highlight the controller, and press F2 for Operations.

If the drives are unconfigured (and the Create Virtual Drive option is not selectable), perform the following from the F2 menu:

1. Select Clear Configuration, then press Yes to clear the configuration.

2. Select Make JBOD (Just a Bunch Of Drives).

3. Select Make Unconfigured Good.

Select Create Virtual Drive and press Enter.

For the RAID Level option, select RAID 5.

Tab to the Drives area. For each hard drive that you want to add to this virtual drive, select the hard drive by pressing the space bar.

Enter any name for the RAID.

Select Advanced.

Set Read Policy to read ahead = always.

For the Write Policy, select Write Back with BBU -if you are using a RAID card with SuperCap (RAID-9266CV), for example..

For the I/O Policy, select Cached.

For the Disk Cache Policy, select Enable.

Tab to the Initialize option and select the option by pressing the space bar.

Select OK. Press Enter.

Select OK and press Enter.

Press Ctrl-N twice to go to Ctrl Mgmt tab.

Press TAB, until the Boot Device field is selected, then press Enter.

Select the drive that you want to use to boot the virtual drive.

Press TAB multiple times to highlight Apply, then press Enter.

Press Ctrl-N until the VD Mgmt screen is displayed.

If your server has more than one virtual drive, repeat this process for each virtual drive.

Login to Cisco Integrated Management Controller.

From the navigation bar, choose Cisco 12G Modular RAID controller.

Select Physical Drive Info from the menu.

Select all drives and mark them as unconfigured good.

Select the Controller Info menu.

Perform the following for each virtual drive in BE6M/H and BE7M/H.

1. Select the Create Virtual Drive from Unused Physical Drives link.

2. Select the RAID level as RAID 5.

3. (Optional) Update the RAID name.

4. Select the number of drives from the available physical drives.

   • BE6M M5- all 6

   • BE6H M5- all 8

   • BE7M M5- for each of the 2 virtual drives, 7 disks

   • BE7H M5- for each of the 4 virtual drives, 6 disks

5. Set Access policy as Read Write.

6. Set Read policy as Always Read ahead.

7. Set Cache policy as Cached IO.

8. Set Disk Cache policy as Enabled.

9. Set Write policy as Write Back Good BBU.

4. In the Actions area of the Virtual Drive Info tab, click Create.

5. Complete the following fields:

1. Click and drag all 3 disk drives from Available Drives table to Selected Drives table. If you don’t have three disk drives, your hardware configuration does not match the Tested Reference Configuration.

2. In RAID Level drop-down list, select RAID 5.

3. Set Strip Size to 64 KB.

4. Set Drive Cache to Disable.

5. Set Access Policy to Read-Write.

6. Check/enable Set this Virtual Drive Bootable.
