Moving mounting points from one Linux server to another
An old server needs to be put down...
The new one needs the old servers mounting points.
I copy the information from the fstab file to the new one yet not sure what else needs to be done.
I need this in the new Ubuntu v14 server:
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p5 232M 156M 65M 71% /
tmpfs 507M 0 507M 0% /lib/init/rw
udev 10M 60K 10M 1% /dev
tmpfs 507M 16K 507M 1% /dev/shm
/dev/cciss/c0d0p2 70M 26M 41M 39% /boot
/dev/cciss/c0d0p6 3.3G 2.4G 674M 79% /usr
/dev/cciss/c0d0p7 123G 99G 24G 81% /var
/dev/cciss/c0d0p8 6.3G 2.1G 3.9G 35% /home
smac-blah01:/storehistory
1.5T 1.3T 264G 83% /var/local/pos
smac-sancs01:/snap03 394G 302G 93G 77% /srv/snap03
//172.16.255.20/dax_data
144G 37G 108G 26% /var/local/dablahx/daxdata
//172.16.255.20/proddata
144G 37G 108G 26% /var/local/dablahx/proddat

Many things do not make sense.
Mounting points are localized to the local server. One matches mounting points when application/services are migrated from one to another and one wants to maintain configuration.
You have an external SAN NFS server
more /etc/fstab
external resources such as the SAN/SNAP have to be configured to allow the new server to access the same resources with the same settings. Note depending on the type of access, (NFS/SAMBA) you can have multiple hosts accessing/mounting the same resources. ISCSI and FC you can only have one resource accessing/mounting the LUN..
df -h does not
what is the df -h from the old versus the new?
Unless you are cloning the old one from the begining, I am not sure what your difficulty is.
Adjust/adapt to what you have unless you can reinstall the new in exactly the same layout as the old......

This looks like an HP Proliant DL360 (or similar) with RAID 5 with 3-4 72GB high speed drives.
If that's true, then when you setup the new server, you have to partition the main system to account for these:
/dev/cciss/c0d0pX
The remainders (as arnold says) are network mounts. These should be in /etc/fstab, but (as you say) you copied those over. Do the directories actually exist on the new server? (If not, there is nothing to mount).
What does mount on both machines say?

Additionally, if the new server is a different server, with different controllers, the /dev/cciss/ devices will show up completely differently. But, I think its irrelevant to what you're probably trying to accomplish...
Okay,
I did not make the best question. Sorry and thank you for your time with this.
From old server what I need is this:
mount:
smac-blahblah01:/storehist
smac-Blahblah01:/snap03 on /srv/snap03 type nfs (rw,hard,intr,tcp,rsize=32
//172.16.255.20/dax_data on /var/local/dax/daxdata type cifs (rw,mand)
//172.16.255.20/proddata on /var/local/dax/proddata type cifs (rw,mand)
