On a server HP PROLIANT ML 35 on RAID5 (3 disk) i want to add one disk , i have insert the new disk and now i find a new logic unity2 on my SAS MODULE RAID5.

I wanted to add this new disk to the first logic unity1.

How can i do that.

Merci

First you have to check if your E200i has the BBWC feature. Without BBWC you can not expand an existing LUN.

Second, there is something that is not consistent with your attachment and with what you are sayng. The first Unite logique appears to be a RAID5 LUN made of 3 146GB disks. The second LUN appears to be made of 3 72GB disks.

I don't think the new disk that you inserted is configured yet.

So check if you have BBWC and post the the physical view (disks) of the E200.

Merci for the answer

this is what i see on the ACU

En vue physique j'ai : PHYSICAL VIEW

Smat array E200i sur le connecteur incorporÃ©
- SAS MODULE RAID A.
Disque 146 gb SAS Ã port1 : boite 1: baie1
Disque 146 gb SAS Ã port1 : boite 1: baie2
Disque 146 gb SAS Ã port1 : boite 1: baie3
Disque 146 gb SAS Ã port1 : boite 1: baie4

En vue logique j'ai : LOGICAL VIEW
Smat array E200i sur le connecteur incorporÃ©
- SAS MODULE RAID A.
UnitÃ© logique 1 (279964 MB ) RAID5
UnitÃ© logique 2 (139979 MB ) RAID5

The first Unite logique is a RAID5 LUN made of 3X146GB disks.
The second Unite Logique is a RAID5 made of 1X136GB disks.

Totaly four disks of 136 go

merci

Based on the physical layout, it appears that the new disk was added to the existing array group and the new LUN was created in the same array group. The new LUN is laid over all 4 disks and not just the new one.

Ensure that the new LUN is NOT in use and delete it. Then if you have BBWC you can expand the old LUN. After you expand the old LUN, you have to expand the OS (windows?) partition. (In windows you use the diskpart.exe utility). The LUN expansion and the OS partition expansion are two separate steps.
