Hi guys, i am getting this above error in my syslog.........how do i take a backup of current disk .....

[RAC_1]

As it says, execute command to know what is happening with the disk.

/opt/resmon/bin/resdata -R 153354242 -r /storage/events/disks/default/0_0_0_2_0.6.0 -n 153354243 -a

Can you do diskinfo/pvdisplay on that disk?
dd if=/dev/dsk/cxtxdx of=/dev/null bs=1024k

Does it return any error?

To take backup onto tape you can use many commands.
tar (gnu tar and not hp tar. it has limitation of 8gb)
fbackup
man fbackup for details.

Hi jhingoor,

You need to check it the full description of EMS event notification first by running the command :

/opt/resmon/bin/resdata -R 153354242 -r /storage/events/disks/default/0_0_0_2_0.6.0 -n 153354243 -a

OR just check /var/opt/resmon/log/event.log, check the last event on the particular time (same as the time on the syslog).

If you already got the full description, check the recommendation for this issue. Check also with ioscan and diskinfo :

# ioscan -nfCdisk
# diskinfo -v /dev/rdsk/cXtYdZ

cXtYdZ is the respective device file for the disk that having problem on event.log

Can also run the 'dd' command to test the disk as RAC refer to you.

For backup, you can use SAM to backup the disk (same as fbackup command), as long as the disk still accessible. If the disk is not accessible anymore, you just need to pray.

BTW, here is the good document for disk :

Hope this information can help you.

Cheers,

Hello jhingoor,

Execute the command as shown in your syslog and find the disk. Check the disk from "ioscan" and get the Cxtxdx value. Then identify the LVM part of it and check if you can identify any issues. If it is a external disk or LUNs from your storage array, I would recommend yo to check the array for the disk in question.
