Re: Testing In RAID Array (MegaRaid)

My set up is similar to yours except that I have a 3ware 9690SA RAID card.

 

I found that the port numbers were NOT persistent across reboots (WTF?), so I had to write a script (available on request) to re-generate smartd.conf on boot (smartctl –scan doesn’t get you the port numbers).

 

My smartd.conf entries look like this:

/dev/twa0 -d 3ware,12 -H -l selftest -l error -s (O/../.././(00|06|12|18)|S/../.././01|L../../5/01) -m [email protected]

/dev/twa0 -d 3ware,13 -H -l selftest -l error -s (O/../.././(00|06|12|18)|S/../.././01|L../../5/01) -m [email protected]

/dev/twa0 -d 3ware,15 -H -l selftest -l error -s (O/../.././(00|06|12|18)|S/../.././01|L../../5/01) -m [email protected] <mailto:[email protected]> 

 

Good luck,

Graham.

Subject: [smartmontools-support] Testing In RAID Array (MegaRaid)

 

Hi All,

 

Just started researching about Raid / disk monitoring and I seem to be finding a mix of conflicting and outdated data for my setup.

 

Server is running 4 x Intel SSD behind a MegaRaid Controller. I am trying to configure smartd to to run daily short tests and once a week on Sunday at midnight a long test on each drive.

 

I see this example:

 

#/dev/sdc -d 3ware,0 -a -s L/../../7/01

#/dev/sdc -d 3ware,1 -a -s L/../../7/02

#/dev/sdc -d 3ware,2 -a -s L/../../7/03

#/dev/sdc -d 3ware,3 -a -s L/../../7/04

 

Which would be suitable so something like

 

#/dev/twa -d sat+megaraid,4 -a -s L/../../7/01 -m [email protected] <mailto:[email protected]> 

#/dev/twa -d sat+megaraid,5 -a -s L/../../7/02

#/dev/twa -d sat+megaraid,6 -a -s L/../../7/03

#/dev/twa -d sat+megaraid,7 -a -s L/../../7/04

 

 

Does that look somewhat correct? I am still researching the other flags so I know what to add for when it should send me an e-mail.

 

Here are some outputs from my server:
