[gpfsug-discuss] GPFS autoload - wait for IB portstobecomeactive

[IBM Spectrum Scale]

This means that the stripe group descriptor on the disk dcs3800u31b_lun7 
is corrupted.
As we maintain copies of the stripe group descriptor on other disks as 
well we can copy the good descriptor from one of those disks to this one.
Please open a PMR and work with IBM support to get this fixed.

Can someone provide some clarification to this error message in my system 
logs:
mmfs: [E] The on-disk StripeGroup descriptor of dcs3800u31b_lun7 sgId 
0x0B00620A:9C84DF56 is not valid because of bad checksum:
Mar 26 12:25:50 mmmnsd2 mmfs: 'mmfsadm writeDesc <device> sg 
0B00620A:9C84DF56 2 /var/mmfs/tmp/sg_gscratch_dcs3800u31b_lun7', where 
device is the device name of that NSD.
I’ve been unable to find anything while googling that provides any details 
about the error.   Anyone have any thoughts or commands?
We are using GPFS 4.2.3.-6, under RedHat 6 and 7.  The NSD nodes are all 
RHEL 6.
Any help appreciated.
 
Thanks
