Nexus 93128 bootflash recover

[CSCO11177789]

Hello;

We trying to fix bootflash corruption but one of stage we had

switch(boot)# format bootflash: check-filesystem
This command is going to erase the contents of your bootflash:.
Do you want to continue? (y/n) [n] y
Sorry, user root is not allowed to execute '/isanboot/sbin/format-bootflash -c' as root on (none).
switch(boot)#

Before this action we want to copy software from tftp to bootflash but it gives error like this;

Destination: error opening bootflash: Device unavailable or corrupted

Is there any solution ?

Best regards
