Re: new disks

Can you tell which Disk Array you have ?
How much capacity of Disks you are thinking of adding and mirroring in the Array?

Re: new disks

Yes you can add those disk in place of 73Gb disks. 146GB/10K Ultra 320 drives are supported on DS2300. Remember , DS2300 does support Ultra 320 connection speed. It will operate at Ultra 160 speed only with those drives.

You have to take backup of you data of 73GB disks first , then you have create a new VG and required lvols with those 146GB disks and restore your data.

Re: new disks

That is great. I want add a new LV to it. Then move the data to the new LV. Is this the best way? I will add two and use one to mirror the other.

Oops!!!! Sorry
Slipped out "not" in my last reply.
DS2300 Does Not support Ultra 320 connection speed.

But Ultra 320 drives would work in it at Ultra160 Speed.

I am not sure what you wanna do exactly and what sort of configuration you have. I guess you have all 73GB disks installed and all have some data. If you want replace two of them with 146Gb drives, then backup your data and create a VG and LVs , restore data and mirror them.

Yes you can if it is possible in the system setup.
