Operating Systems AIX Source port on AIX for NAS is same? Post 303018128 by anil1000 on Tuesday 29th of May 2018 03:32:54 PM

In AIX system, we face NAS issue on system.

Working:-
Code:
root]df -gt
/ 
/boot
/var
10.208.108.9:/data /data <- NAS  mount point


Not working:-
Code:
/
/boot
/var
NFS is trying to mount using 10.208.108.9

in AIX , if we type "nfso -a"
we see some parameters, in which there is one which states that
Code:
nfs_use_reserved ports= 1 (use ports less than 1024)
nfs_use_reserved ports= 0(use ports more than 1024)

however keeping "0" value here does resolve the NAS issue of mounting but it is not safe as per SCD to allow NAS coomunication to happen between aix client and storage on random ports.

but when we keep 1 we face the issue as it only takes 1021 1022 1023 ports as source port for mounting.

so my question is , can we specified that only 3000 to 3020 ports be used for NAS mount points?

Thanks
