<div dir="ltr">I think it wants a raw device, not a partition. Also, I noticed you're using two 7tb partitions on a single 14tb lun. You're going to really hurt your performance by doing it that way. Just my $.02.<br>

Hi,<br>
<br>
I am a neophyte trying to benchmark new hardware for a Lustre setup.<br>
I got the Lustre IOkit noarch rpm and installed it onto the OSS. I<br>
edited the file /usr/bin/sgpdd-survey (attached) to meet the<br>
description of our OSS (RAM is 16Gb, sample new hardware detected at<br>
/dev/sdg).<br>
<br>
My initial running of sgpdd-survey produced the following errors:<br>
[root@oss4 ~]# sgpdd-survey<br>
Can't find SG device for /dev/sdg1, testing for partition<br>
/usr/bin/sgpdd-survey: line 105: CAPACITY<br>

0x200: syntax error in expression (error token is "trying<br>
0x200")<br>
/usr/bin/sgpdd-survey: line 106: [: ==: unary operator expected<br>

System Info:<br>
[root@oss4 ~]# uname -a<br>

<br>
The physical device is there. I did format it into two 7Tb partitions<br>
just to give it an earlier test. Do I have to un-format it for<br>
sgpdd-survey?<br>

Any advice for testing a new system with sgpdd-survey?<br>
