Internal Disk was configured as RAID 0
We have two (HP DL380 G5) Servers. In both servers we have installed RHEL 5.4. But when we run â ./hwraidinfoâ & â hwraidstatusâ commands it shows that internal disk was configured as RAID 0. Please check the attached output with this thread. Please verify & confirm me whether or not is there any possibility of complete data lost if one of the disk faulty
hwraidinfo:
XXXXXXXXXXX
#!/bin/sh
SLOTLIST=$(hpacucli ctrl all show | \
grep Slot | sed -e 's/^.*Slot //g' -e 's/ .*$//g')
for i in $SLOTLIST
do
echo
hpacucli ctrl slot=$i show | grep -v "^$"
echo
hpacucli ctrl slot=$i ld all show | grep -v "^$"
hpacucli ctrl slot=$i pd all show | grep -v "^$"
done
echo
hwraidstatus:
XXXXXXXXXXXXX
#!/bin/sh
SLOTLIST=$(hpacucli ctrl all show | \
grep Slot | sed -e 's/^.*Slot //g' -e 's/ .*$//g')
for i in $SLOTLIST
do
echo
hpacucli ctrl slot=$i show status | grep -v "^$"
echo
hpacucli ctrl slot=$i ld all show status | grep -v "^$"
hpacucli ctrl slot=$i pd all show status | grep -v "^$"
done
echo

Re: Internal Disk was configured as RAID 0
you have 2 logical drives with raid 0.
why dont you recreate one logical drive with raid 1 with striping and install the OS on it

Re: Internal Disk was configured as RAID 0
Thanks a lot to guide me. Can you help me how can i mirror disk /dev/cciss/c0d0 with Disk
/dev/cciss/c0d1 (May be soft RAID)
But Disk /dev/cciss/c0d1 is already RAID 0. This RAID is configured with P400 HP Smart controller.We cannot format the disk because this server is now in Production.
Thanks
Minhaz

Re: Internal Disk was configured as RAID 0
you can very well format it.
you can use use fdisk -m dev/cciss/c0d1
and yes you can do a software mirror.
the best thing was to create a raid 1+0 initially before installing the OS.
even now if the server is new you should consider doing a HW raid 1+0 and install OS again
