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
