Re: A 1tb mount point need to be create from dmx 3000
If none of this makes any sense, you probably need a consultant to help you with the tasks and there are several different technologies (EMC, Brocade, partitions, LVM utilities) involved.

Re: A 1tb mount point need to be create from dmx 3000
Thanks for your reply...........
But i knew it. storadge is already configured and zone is also there in san. Probelm is that i need to free some lun from my another hp server (lv, vg and unmapping done) to discover it on my superdome server.

Re: A 1tb mount point need to be create from dmx 3000
The the SAN must be changed to remove the LUN from the other server and present the LUN to your superdome partition. At that point, the instructions above will get the LUN operational.

Check the step to allocate LUN from DMX to Superdome.

LUN Allocation Steps from DMX..
you can allocate LUN through SYMCLI & ECC
STEPS Through SYMCLI
1.View the UNCONFIGURED space on the symm(DMX)
symconfigure -sid xxxx list -freespace -units MB
2. Create_2-way_[sid]_req[EMC request DB #].txt
create dev count=xx, size=17480, emulation=FBA, config=2-way-mir, disk_group=x;
#symconfigure -sid XXX -f /tmp/filname.txt preview -v
#symconfigure -sid XXX -f /tmp/filname.txt prepare -v
#symconfigure -sid XXX -f /tmp/filname.txt commit
3 form meta_[sid]_req[EMC request DB #].txt
form meta from dev xxx config=striped, stripe_size=1920;
add dev yyy:zzz to meta xxx;
#symconfigure -sid XXX -f /tmp/filname.txt preview -v
#symconfigure -sid XXX -f /tmp/filname.txt prepare -v
#symconfigure -sid XXX -f /tmp/filname.txt commit
4.List of available devices that are created but not assigned to the front end FA├в s.
#symdev -sid xxx list -noport -nobcv
5.Find the next VBUS TID LUN to required FA (For Ex: - dir 9a -p 1)
#symcfg -sid XXX list -address -available -fa 08A -p 1
Director Device Name Attr Address
---------------------- ----------------------------- ---- --------------
Ident Symbolic Port Sym Physical VBUS TID LUN
------ -------- ---- ---- ----------------------- ---- --- ---
256D Not Visible (M) 4 01 006
2575 Not Visible (M) 4 01 007
- AVAILABLE 4 03 001 *
(*): The VBUS, TID, LUN address values represent a gap in the
address assignments or are the next available address in
the run
You can use next VBUS TID LUN - AVAILABLE 4 03 001 *
vbus=4
target=03
lun=001
6.Create a file:- /tmp/filname.txt
map dev yyy to dir 09A:1 vbus=4,target=03,lun=001;
map dev zzz to dir 09A:1 vbus=4,target=03,lun=002;
#symconfigure -sid XXX -f /tmp/filname.txt preview -v
#symconfigure -sid XXX -f /tmp/filname.txt prepare -v
#symconfigure -sid XXX -f /tmp/filname.txt commit
8. Adding LUN Masking (assigning LUNs to host HBA├в s.
#symmask -sid xxxx -wwn 10000000cxxxxxxx -dir xx -p x add devs xxx,xxx,xxx

Re: A 1tb mount point need to be create from dmx 3000
1.unmount the mount point.
2.Remove the LV
3.Remove the VG
4. unmapdev_[sid]_req[EMC request DB #].txt
unmap dev xxx from dir all:all;
#symconfigure -sid XXX -f /tmp/filname.txt preview -v
#symconfigure -sid XXX -f /tmp/filname.txt prepare -v
#symconfigure -sid XXX -f /tmp/filname.txt commit
5, Removing LUN Masking (unassigning LUNs from host HBA├в s)
symmask -sid xxxx -wwn 10000000cxxxxxxx -dir xx -p x remove devs xxx,xxx
now you can map & mask same LUN on another server.
