SYM Devices ID's

Prashant Zanwar_4 — Fri, 03 Feb 2006 17:40:12 GMT

I am sure many folks around would have symmetrix array connected to host.
Here it would be probably easy for folks, if I ask,

- I have multiple paths to metadevices, say 2-3
I want to collect all three devices on a single like having similar SYMID.

===========================================

this is created thru query

sympd -sid 0451 list,

If you observe above, devices are same, like C18 is alternate to C12...

What I want to do is,

if 0043 appears in second column, and repeats again at later in output, i want to club column 1 ($1) for this device, with first output occured. Rest i can ignore.

For example :

/dev/rdsk/c12t3d1 0065 04A:0 01B:D0 2-Way Mir Grp'd (M) RW 17428

/dev/rdsk/c18t3d0 0063 13A:0 01D:D0 2-Way Mir Grp'd (M) RW 17428

these are similar,

i want to print

c12t3d1_c18t3d0 0063 2-Way Mir Grp'd (M) RW 17428

I think it's possible in one single command,
using some awk trick, getline or something..
not sure how to acheive..

I am able to club all similar one after other..
how to take them in one line and produce desire result, if some one can help, will be great.

Thanks
Prashant

Sorry for putting it wrong:
Above example becomes:

/dev/rdsk/c18t3d1 0065 13A:0 01B:D0 2-Way Mir Grp'd (M) RW 17428

/dev/rdsk/c12t3d1 0065 04A:0 01B:D0 2-Way Mir Grp'd (M) RW 17428

then

c18t3d1_c12t3d1 2-Way Mir Grp'd (M) RW 17428

Thanks, please reply..

This is needed to avoind any accidents while choosing free PV's from list.

Thanks and regards
Prashant

Hi Prashant:

Oops, I forgot to tell you how to run it!

# ./syminq.pl file

(or):

# sympd -sid 0451 list | ./syminq.pl

Regards!

That works great..
I really appreacite quick response.
Thanks a bunch..

If possible, can u also tell the way to put VGNAME in the end against the disk used in particular VG?
That will be just a excellant thing..

Thanks

That works great..
I really appreacite quick response.
Thanks a bunch..

I wanted this to be modified further and let the output also have a used disk ID=VGNAME of that disk, if disk is not used, should show as free..

If possible please post answer fot this requirement too..

Thanks
Prashant
