Sudheerrao29 & Jazzman, here is ur answer.

DAE4P – A 4 Gb/s point-to-point Fibre Channel disk enclosure. This is the standard disk enclosure for CX3 UltraScale series storage systems, as well as CX4 storage systems. The only difference between the two is the bezel on the front of the enclosure.

DAE2P – A 2 Gb/s point-to-point Fibre Channel disk enclosure. DAE2, DAE2-ATA, and DAE2P disk enclosures may all be present on CX series storage systems.

Does this apply to VNX too?

Re: LUN and VBUS Mapping for HP-UX

Bill Connolly — Fri, 29 Jul 2011 09:46:51 -0000

I have a script that will generate the mapping sintax for entering the starting address, and the two fa paths on dmx for host only requiring lun addressing.   I was hoping that someone out their had the logic that would count from a starting vbus, target, lun and generate the sintax necessary to read a list of devices and output all the mapping commands.   It was easy for just hosts like vmware, sun, window, aix. but hp with volumeset addressing is more complicated.   thanks my email is bill.connolly@chick-fil-a.com
chick
here is the script to map a list of luns(in heads.out) to be used with symconfigure

/support/storage/bill/scripts-132# cat createmap.out#/usr/bin/ksh# arguements# arg 1 = starting lun# (Alpha must be uppercase)# arg 2 = first FA port in ##:## arg 3 = second FA port in ##:###set -xif [ $# -ne 3 ]then echo "Usage: `basename $0` StartingLun FirstFA SecondFA " exitfi
n=`echo "obase=10;ibase=16; $1;" |bc`for i in `cat heads.out`do        outn=`echo "obase=16;ibase=10; $n;" | bc`        echo "map dev $i to dir $2, lun=$outn;"        echo "map dev $i to dir $3, lun=$outn;"        echo        n=`expr "$n" "+" 1`done

If you know how to do this for hpux.    Please send me a copy to bill.connolly@chick-fil-a.com.   thanks again.

Re: HDS Bloggers Day – Day 1 – Session 03/23/2011

Chadwick James King — Mon, 25 Jul 2011 12:40:27 -0000

Devang,
I hope to learn more about the HDC in our own environment. I am new in some ways and was wondering if you or anyone has actually seen the vCenter plug-in for HDS systems. The biggest problem we are seeing is that when we are doing migrations and LUN provisioning they cannot use a naming convention to reference between the Datastores and the LUNs provisioined. I know there are other tools out there that can help with this and I am sure it is somewhere out there but it seems like there are some missing links from here to there. Any help would be appreciated.

# symld –g newtgtdg rename DEV001 NEWVOL1

You are making the DEV001 on remote host to see as a similar to local ( which will be easy for understanding )

I do not think that is the case....

Sudheerrao29 — Sun, 26 Jun 2011 05:42:33 -0000

i think there is no difference between them......DAE2P it's a 2nd enclosure in the array and DAE3P it's a 3rd enclosure in the array

On windows I used vmware player to run the iso and install directly to a usb disk - if you have a similar tool to vmware player for OSX - it will be more straight forward than this....

Re: EMC Symmetrix Enginuity Operating Environment

storagenerve — Fri, 17 Jun 2011 10:26:29 -0000

Hi,

Thanks for reading the blog.
Enginuity is not a flavor of Unix or Windows, its a custom OS built within EMC for only the Symmetrix systems.

Devang

Re: Converged or Unified

storagenerve — Mon, 13 Jun 2011 23:59:15 -0000

Interesting post Stu. It is interesting to see the blurring lines between server and storage when it comes to HP, atleast the Hardware it runs on is commodity hardware (servers). Though i dont see a them making a move towards unified platforms (file and block) under the same umbrella. It may be possible, they would as next step try to integrate the SAN and NAS offering into a single platform under Store 360.

Re: Converged or Unified

stu — Mon, 13 Jun 2011 14:49:38 -0000

Devang,
In general, I see Unified as multi-protocol (most define it as block+file) while converged is putting together multiple layers of the stack. While HP is probably furthest along with merging server and storage products while EMC and NetApp are doing convergence through the converged stacks with Cisco - my write-up on the options: http://wikibon.org/wiki/v/Conv....
Good to see you at the show and glad to see you posting articles :)
