SMIT PDAM Consistency Check

[unic]

Replaced a failed hard drive in a RAID 5 config. Performed the
Reconstruct function which ran with no failures and the array showed
all 5 drives back online and in optimal state again, but forgot to perform
the "Consistency Check" afterwards. It has been a week now and I'm
just wondering if it was ok to run the Consistency Check anytime
without any adverse effects? And should I just run the check first, or the
check with repair option? My AIX support line is hourly for this machine
so I don't want to use that option.

Thanks!

unic,

If you are refering to an fsck then you have to perform this on and unmounted filesystem, i.e. during non-system hours. I have replaced many drives in RAID 5,10 and LVM mirroring and only used fsck when I have had data corruption, if you want to check do it without fixing the problems :

fsck -n /dev/lv01

This should then put your mind at rest. If you have any errors and are unsure what to do post them into this message.

I found the RAID Adapter Reference Guide and the Reconstruct is sufficient...no need to run the Consistency Check afterwards as any errors would show up with the Reconstruct. In fact, the Consistency Check should be run when there is a system crash or power problems which wasn't the case here. Thanks for the reply though, greatly appreciated.
