Retrieve san configuration issue

Hi All, 


I am now experiencing a strange issue: 
When selecting SAN (switches) configuration to get an overall view of the SAN , the software just goes into a loop without showing any data 

Here are the error.log

Use of uninitialized value $RRDp::error_mode in string eq at /usr/lib64/perl5/vendor_perl/RRDp.pm line 168.
Tue Dec  8 14:55:03 2020: SAN SWITCH : san.pl : load_san failed: ERROR: '/data/stor2rrd/data/BFRCRBSWI002/port19.rrd' is too small (should be 12432216 bytes) at /data/stor2rrd/bin/san.pl
line 2690.
 /data/stor2rrd/bin/san.pl:113

Thanks in advance

    Hi,

    it looks like that rrd file is corrupted.
    We would need to see the output from these commands:

    ls -l /data/stor2rrd/data/BFRCRBSWI002/port19.rrd
    rrdtool fetch /data/stor2rrd/data/BFRCRBSWI002/port19.rrd AVERAGE -s -20min
cd /data/stor2rrd/
./bin/check_rrdtool_stor2rrd.sh

    NOTE: the last command can take some time, so let it work till end and then send us the output

    Hi,

    there is just one corrupted file.

    Remove that file:

    rm /data/stor2rrd/data/BFRCRBSWI002/port19.rrd

    After then:

    cd /data/stor2rrd/
    ./load.sh

    Refresh stor2rrd UI (ctrl+F5).
    Let us know if that helped. Thanks.
