Create RAID 1 on RX6600

[AZayed]

Dears,
Good day,

We ordered a RX6600 with 6 disks and the built in SAS controller. Now, I need to create two RAID 1 volumes but my the system giving me "Bad addresses", what am I doing wrong ?

# sasmgr -N get_info -D /dev/sasd1 -q raid

Mon Feb 7 14:14:46 2011

WARNING: If the disks are of different size,
then the remaining disk space of the larger disk
will be wasted and the volume cannot be expanded.

WARNING: Make sure that the disks are not being
used for BOOT, SWAP, DUMP, LVM, VxVM or any other
purpose.

This operation will overwrite the data on the disks.

Do you want to continue ?(y/n) [n]...

WARNING: This operation may take a few seconds.

Hi

Can you post ioscan -funC disk.
I supposed you boot from other disks

Hi

It looks Ok.
The only thing I append in command is size:

-q size=285000

Regards, Jorge

[AZayed]

Thanks it's now working. Yesterday I used size option but I think the size was large.

Last question, is this SAS controller support Root Disk? Is it better than DiskMirror ??

Thanks

[Jorge Pons]

Hi

Yes, it support.
When you talk about root disk, are you talking about DRD?
DRD is different from Mirror Disk.
DRD is for test boot environment and Mirror is for availability

>> is this SAS controller support Root Disk? Is it better than DiskMirror ??


Yes, such a mirror can be used as boot disk.

Yes, IMHO it is better to such the hardware mirror than the LVM mirror with such SAS disks, because the replacement is much, much easier.

[AZayed]

Hi Jorge,

Actually, I was talking about SAS mirroring. In my case if I need to create a mirror on root disk I will write :

sasmgr add -D /dev/sasd1 -q raid -q level=1 -q enc_bay=1:8,1:7 -q size=286080

Does it work?

[Jorge Pons]

Hi

Yes, it works.

CAUTION: If you do this on your current (non-RAID) boot disks (and you are doing so), the disks will be overwritten and the OS installation is GONE!
