bhayya nuvu ee concept chala confused ga unnavu...basically both has pros and cons but for some environments hard zoning are a real head ache...
and regarding what you said brocade is using all hard zoning.....I don't think so.....because in our environment we have many broacade switches and we no more have hard zones...all the zones we have are soft zones
[/quote]
ok ba, I guess it's the usage of terminology...
anyways it depends on ur interpretation of softzone and hardzone?
If u were to refer your zoning type using identity type, in ur environment what identity type is used ?

I am bit confused now, you have outlined merits over demerits brilliantly however I am bit confused with definition of hardware zoning and software zoning

My understanding of hardware enforced zoning is it is of 2 types
frame based h/w enforced
session based h/w enforced
Software enforced zoning: long gone. Brocade is not anymore using port masking using name server service on software level. I believe due to data security reasons soft zoning was completely binned.
Now they only do Hardware enforced zoning:
H/w enforced uses filtering at port level by ASIC's, filtering filters based on zone config...if communications initiated by hosts that are not in zoning config then port filtering will reject it at hardware level.
Frame based zoning is
zoning done using identity pWWn
zoning performed using identity (d,p)
Zone performed using either pWWN identity or (d,p) but not mixed.

Session based:
all mix fruit juice identity
overlapping

Think ,the differences which u quoted above are for identity types, correct me if I am wrong.
so basically I understand all zoning is hardware enforced in the current times

Right ok, Just one clarification
miru hard zoning /soft zoning ante deni refer chestunnaru ?
..
Official line from Brocade contradicts exactly what you say I am afraid.

Is below what you mean by hard /soft zoning ?

Soft Zone (identity type pWWn) : Zonecreate "Red_zone1", "pWWn;pWWn"

Hard Zone (identity type (D,P): Zonecreate "Red_Zone1", "d,p;d,p"

Then I am afraid to say you are using wrong terminology , just read zoning documentation from Brocade site and what I said stands true.
So therefore there is no official soft enforced Zoning , it's all implemented now on hardware level hardware enforcement type

Could you kindly clarify by referring to documentation

nenoka document chesanu "how to reclaim storage from Symmentrix" ani....[color=#ff0000][b]e procedure server ni life cycle (decommission) chesina tharuvatha follow ayyedi....[/b][/color]


[b][color=#000000]How to Reclaim Storage from Symmetrix[/color][/b]

[u][b][i]Tools to open:[/i][/b][/u]

CMD Prompt (to ping host)
Cisco Fabric/Device Manager
Symmetrix Management Console (SMC)

[u][i][b]Steps to validate host availability:[/b][/i][/u]

Before you begin, please have as much information you can get from past Altiris requests, emails, Admins, etc. The host you’re about to unmap / unmask from DMX/VMAX, will highly depend on the information

1) Ping the host
a. Reply: Research to see if system is being used or has been renamed
b. No reply: Continue with next steps
2) On Fabric Manager, search for the WWN
3) On Fabric Manager, search for Enclosure name
4) On SMC, search for host under host alias (highlight Host Alias)
a. You will need to be sure and sort by Name then scroll to locate host.
5) Look for initiators under host alias and check whether they are “Logged In” or not.
a. Yes: Stop this process and investigate
b. No: Continue with next steps.
6) Once we’ve validated to move ahead with reclaiming (either from UNIX/NT Admins, please move on to the next step.
7) Unmask both paths
[b][color=#ff0000]8) Unmap (note: Data will be lost!)[/color][/b]
9) Remove Host Alias
10) Goto Device Groups > right click on host > DG/CG Management > Delete Group
 
Clean-up on the Cisco side

We will complete these steps only after we reclaim space on the storage side.
1. On Cisco Fabric Manager, Edit Local Full Zone Database and remove Zone information
2. Distribute and Activate the Zone changes
3. On each Cisco Device Manager, disable the port, clear out the information in the description and clear out the VSAN settings.

[b]NOTE: Okavela, server ni decommission cheyadam ledu, only storage reclaim matrame cheyali ante, just 7th step nunchi start chesthe chalu.....eppatikayina unthundi ani motham procedure cheppa...[/b]

[girishv]

So, device ni UNMAP chesthe data destroy avuthundi.....NetApp lo ayithe aggregate ni destroy chesina tharuvatha a disks spares loki kanipisthayi, a spares ni zero up cheyali with the command [b]disk zero spares. [/b]Symmetrix lo em avasaram ledu, oka sari unmap chesthe chalu, data will be gone, [b]so make sure you are unmapping correct devices[/b]

e requests ni [b]"Storage reclamation [/b]or[b] deprovisioning" [/b]antaru.

Oka particular server ki e luns ichamo ela thelusthundi?
Device groups create chesthamu kada....go 2 device groups and look for that particular server...andhulo devices untayi....but u need 2 make sure that device groups up to date unnayi ani....it is the best practice to update device groups whenever u provision storage.....

oka vela device group up to date ledu anuko, it is not end of the world, go to the [b]host alias[/b] under [b]symmetrix masking[/b], click on the server from which you need 2 reclaim storage, right side window lo [b]initiator(s)Port(s)[/b] open avuthundi....edho oka initiator meeda click chesthe kinda[b] general[/b] and [b]devices[/b] ani 2 tabs kanipisthayi.....click on devices 2 know which devices were assigned to that server.....

inka doubts unte let us know

[girishv]

Okevela nuvvu symcli prefer chesthe use this command to know which devices were assigned to that server

CLARiiON ki scene ayipoyindi boss, me vadini VNX gurinchi chepamanu..
VNX is the update for CLARiiON. In VNX you can have both SAN(Block) and NAS(File).
so dani meda concentrate chestey better.

nuvu CLARiiON ki NAVISPHERE software(GUI) ki use chestey..ikada VNX ki UNISPHERE(GUI) use chestavu..
inka details kavali antey contact CITI.
