RAID 5 question
I only have a DS2300 disk array together with a L class server. Can I do RAID 5 without the any RAID hardware adapter and VXVM software? Thanks.

Re: RAID 5 question
LVM do not support this. It supports stripping but not raid5. It requires a Hardware Raid Adapter or a VXVM product.

Re: RAID 5 question
No, not without VxVM, there was no support for software RAID in LVM. The only option (whitout a RAID card) is mirroring.

Re: RAID 5 question
The '-I -i' and '-m' options of lvcreate are mutually exclusive at this point. If you want true striping and mirroring then you have to go the VxVM (Veritas Volume Manager) route.

Re: RAID 5 question
I may plan to integrate a raid adapater (PCI-4-channel-ultra160 controller) in my L3000 server. But if without the VXVM software whether it can work with my DS2300 disk array ?
If can work, how much work I need to do after install the adapter? Something like what's the other software i need to install besides the driver for raid adapter? Any other configuration? Can someone advice me?
thanks.

Re: RAID 5 question
After inslatting the RAID adapter you need to install the driver/utility for that card. Once done you need to configure all your disks from the scratch to configure new Logical devices whcih will be visible to host. You may leave OS part as it is and can have only data onto to DSXXXX array.
