raid -stiping

[Jeff Hagstrom]

How do I know if my system has raid 5? Where can I look, in sam or anywhere else to see if it is setup. We had a drive go bad, replaced it and low and behold everything was replaced.

Depends on what kind of hard drive it is. If it is an internal disk then you can look at the LVM configuration of the other disks to get an idea of the mirroring/striping that was used. If it is an external disk then contact the storage folks who set it up in oder to find out its RAID configuration.

cheers!

Jeff,

Usually people that are running raid 5 is at the hardware level, let it be in the server or external storage.

If in case of doubt you can always check with hardware team.

If internal, you should have at least 3 hard drives available, if external same rule applies.

Regards,

Jaime.

Jeff,

It depends on the Volume Manager used. And I trust this question assumes your system uses simple untprotected directly attached disks right (not Hardware based arrasys on a SAN which most likely are already RAIDed internally)?

LVM:

vgdisplay -v vgname


VxVM:

vxprint -Aht


It will show the level of RAID protection if any exists.
