3rd SATA Disk on HPDL140G2?

[Ray Van Dolson]

Background:
Have a DL140G2 system with two SATA drives configured in a software RAID1 configuration.

Unfortunately a partition on each disk has gone bad, meaning we can't just throw in a new disk and have the array rebuild itself.

We'd like to add a 3rd SATA drive as a spare so it can get rebuilt correctly.

However it appears the DL140G2 has only two onboard SATA channels. What suggestions do you have as how to add a 3rd SATA disk to the system? Is our best bet a PCI SATA controller card?

The system is running RHEL4.

How do you plan to add a third drive to this server? You have a space limitation...

Maximum Internal Storage:

Non-Hot Plug SATA 1TB 2 x 500GB
Non-Hot Plug SCSI 292GB 2 x 146GB

Even if you get the 8 Port SATA RAID controler (HP 8 Internal Port SAS HBA with RAID -> 347786-B21 ) which is the only option for this server, you cannot allocate any other drive inside the server..

Hanging out the side is fine. This is for recovery purposes only remember? We just want to get the 3rd disk re-sync'd then we can get rid of the bad disks.

This is the exact approach we ended up using. Had to use an external drive array though.

Thanks anyways.

By channels are you referingto cables or real channels? because teh 8 port SATA controller option 347786-B21, hast 2 channels too, but it has 4 ports (each port is splitted into 2 terminations).

Now, about how to provide power to this 3rd drive... no idea...
