Note:

At this time, the hard disk 252 7, that is, the hard disk with slot number 7, has just been plugged into the hard disk without raid status, and do raid0 to the hard disk at this time.

Do the VD of raid0 to 252VOL7

Storcli64 / c0 add vd r0 size=all drives=252:7 wb direct strip=128

Note:

R0 means raid0, the default ceph "we choose" single disk to do raid0, there are R1 R5 and other raid level.

Size=all has all the space available to do the vd;..

Drives=252:7 corresponds to the eid/slt of the new disk. If multiple disks are used as VD, you can write the corresponding format of 252 VD.

Slt.

Wb stands for write_back mode and wt for write_through mode.

Direct means that DirectIO read operations are not cached to raid card cache, corresponding to CacheIO will read hot data

Cache to the cache of the raid card.

Strip=128 stands for the difference between "128kb" and "single disk". Multiple disks need to be considered to make raid0, as long as it is kept with other disks.

Storcli64 / c0/vall show all can see the strip size of other vd.

After adding vd, you can see that storcli64 / c0/vall show already exists in vd

If you want to delete VD2 at this point, confirm the corresponding system partition of VD2. Here is sdc and the partition sdc1... of the device. It is not mounted to make it work.

Delete VD command: storcli64 / c0/v2 del force

After deletion, VD is gone.

The Cache attribute of VD2 is RWBD, which is the comment under the output: Read Ahead, WriteBack,Direct IO.

1. Change the cache policy of VD2 to WriteThrough mode:

Storcli64 / c0/v2 set wrcache=wt

At this point, if you look at the status of v2, the Cache column will be RWTD.

You can set various configuration items

two。 Modify VD2's cache read-ahead policy = to NR mode:

Storcli64 / c0/v2 set rdcache=NoRA

At this point, if you look at the status of v2, the Cache column will be NRWTD.

Set the hard drive to jbod mode online

1. Verify that the raid card holds jbod mode and turns on jbod mode:

Storcli64 / c0 show all | grep-I jbod

[root@SZ × ×-2] # storcli64 / c0 show all | grep-I jbod

Support JBOD = Yes

Support SecurityonJBOD = No

Support JBOD Write cache = No

Enable JBOD = No

Note:

You can see that support JBOD = Yes, which means that the raid card holds jbod mode

However, Enable JBOD = No, which means that the current raid card does not have jbod mode enabled. You need to enable raid mode at this time.
