JBOD and UGOOD

2019-10-21, 22:01 PM

Drives need to be on U_GOOD state to be configured on a RAID volume.  
Drives on JBOD state cannot be used to create a RAID volume.

When drives are configured on a RAID volume, the state changes to ONLINE.

There is no functional problem when some drives are configured on RAID volumes and other are left as JBOD.

Dear,

As far as I know, the default HDD mode is JBOD(Just a Bunch Of Disks) on thinksystem. This is normal.

Yes, if you would like to make raid storage, you need to change the HDD mode from JBOD to Ugood first.

Usually, you couldn't/shouldn't mix them in one raid array. In one array, the HDD mode should be same. Thanks.

 

Karl
