There is a total of 5 disks in that machine.




Question:
- is there a way for me to see if those disks are mirrored or not?


on the lvm part i am okay; however i have not worked with redhat.

the hardware is: DELL 2850.


thank you all for the help.

Do these links help (especially the third)?

hi ehwak,
thank you for your reply, being sick i was absent few days, just got your email.
i saw those links but i am still kind of confused on the actual mapping of drives and if they are mirrored or not.
for example, on the dell machine, there are 5 drivers (one with the amber light), and by inspections of vg group, it shows one logical voluem with two disks, so i am certain there is some kind of mirroring/raid. i believe to be hwe raid. but this is what i am not sure.
my plan is:
1. halt the system
2. remove the disk with the amber light.
3. disk plug in the new disk.
4. and wait to see if the raid populates the new disk.

BTW, i was looking in some google sites, and saw that the 0x40000 is due to high temperature, have you ever seem something like that ?


thank you very much,

./antonio/.

closed thread.
the tech came in and told me to ignore the kernel warning. he just replaced the drive with new one. it was a hardware raid 5, so there was not much problem on fixing.
thank you all,
