Help with running Smart Checks on more drives than 25

[AuroraAnea]

Hello,

 

Hope everyone are having a good day!

 

I have successfully been running quick smart checks on my drives using user scripts and this script:

#!/bin/bash
for i in {b..z}; do
    smartctl --test=short /dev/sd$i
done

 

But this only work with drives up to 25 (sdz)

And i have 26 drives installed at the moment, which put the identifier up to sdaa, and the script doesn´t work if i set it as:

#!/bin/bash
for i in {b..aa}; do
    smartctl --test=short /dev/sd$i
done

 

Any hints on that i am doing wrong?

try this instead

#!/bin/bash
for disk in $(lsblk -I8,65,66 -ndo name); do
    smartctl --test=short /dev/${disk}
done

 

it lists names of all devices using lsblk, where major device numbers as 8, 65 or 66 (sd*), then loops through them

Thanks for the quick reply, that solved it, does exactly what i needed.

 

Thanks again and have a mighty fine day!
