exploitM — Wed, 24 Apr 2019 09:48:34 GMT

Hi,

I made a mistake, I have added 2 new disk to rhe worng ld, It had transformed the ld1 in Raid 10. Now I try to remove the disks from Array A to assigned them to Array B, but it doesnt work.

Let me know if it's possible without breaking the OS ?

hpssacli ctrl slot=0 array A remove drives=2I:1:5,2I:1:6

Hello ,

It is theoritically possible to split RAID 1+0 to RAID 1.

However, it cannot be done in Online Mode. You would have to reboot the server and boot to the HPSSA in offline mode and then you will see an option to split the Mirroring.

However, it is recommended to take a Backup of the Data before you proceed with the Update
