Yes, why cant you have 30 volumes on 37 disks? Are you sure that its not the case?
If yes, please see below and let us know.
?Question?
How many disk do you actually have?
What is the version of VXVM you are running?
What is the OS? Version?
What is the model of server?
What is the configuration/algorithm used for of DMP?
There are 4 storages attached to the server wid solaris 10
al 4 are sun 6140
i have 2 SAN switches for 4 storages as i cn max add 3 storages
one volume has been assigned to the disk
i cn c dat in storage too
there is no problem from storage end
As far as i knw only those LUNs are shown in vsdisk list output that you hv assigned in the storage
plz correct me if i am wrong here
Now as i hv 2 SAN switches 4 paths should exist for each disk
bt nw whn i chek the paths assigned
via luxadm
i gt the following output
jest chek the last 7 logical disk ( they hv 2 paths )
i am right nw very cnfused .....
are these 2 problems interrelated or which is due to which and DMP has nt been assigned as i need the logical disks to assign 2 diff disk grps
i dunno if i hv explained myself very clearly
plz lemme knw
this is d only prb whr i hv been stuck for quite a time
In total i hv 120 volumes for 4 storages ie 30 each
its working fine for rest of the three storages
and frm whr do i knw the version of VxVm plz lemme knw
Well, as of I know, the vxdisk list command only displays the names of the
native multipathing metanodes, and cannot display legacy names
for the devices. (i.e) There are no alternate link to the disk listed on the vxdisk list command.
As of I believe, its gonna be with DMP end only. Were there any HW changes to the server bro? Or, any changes to DMP configuration?
Are you using active/active?
Hmm... Please try the below bro..
#vxdisk path (check this command out)
# vxdmpadm getlungroup dmpnodename=c#t#d#
This could give us some more information about the paths configured.. Please make sure we are finding the paths for all the disks)
Oh yea, controllers changed. Ummm, the attached output seems to be fine bro.. But, not practically.
It shows up 482 out of which 2 are root/rootmir.. So, remaining 480. Actual Disks should be 120 as each disk has 4 paths. Per your earlier post, 4 storages with 30 each. So, 30*4=120. Path's appear to be fine ENABLED. However, if we see it clearly, there are few disks only with 2 paths..
Seems there is a conflict inside..
Let's do like this.. Proceed checking the controllers..
#vxdmpadm listctlr all
Make sure that all the controllers are showing up and fine. Get the controller name and status...
#vxdmpadm getsubpaths ctlr=<Controllername>
Check if the controllers are enabled and active. (It also depends on the DMP layout/algorithm you are using)
Find the controllers which are disabled, perhaps, this could give us some information.. I would also give priority to the controllers which were changed recently.
From what you have described, you seem to be misunderstanding the command vxdisk.
the output of "vxdisk list" will only show you the physical disks that it can see.
if you have 10 disks with thirty volumes, then vxdisk list will show you ten disks. If you have ten dual pathed disks with no multipathing software configured, then you will see twenty disks.
I think he is referring to disk as volume. As of I understand from him, he says that he should be having 30 disks on vxdisk output and he is having 37 disks showing up instead.
Getting deep into it, there are 30 volumes on those 30 disks!
Am I right bond_ankur? Please let us know.. Since, as I said earlier,
Yes, why cant you have 30 volumes on 37 disks? Are you sure that its not the case?
You can always have 30 volumes on 37 disks or 37 volumes on 30 disks!
And I also believe,
There are no alternate link to the disk listed on the vxdisk list command, please correct me if am wrong.
dats wat d problem is ,,,,as u cn also c i dat hv 4 storages and for rest for them its 30 vlumes on 30 disks!!
y for this storage its acting weird !!!
m attaching the puput for format too
My problem is i hv to assing these ASM for my oracle as per the LUN numbers and for this storage i m getiing two LUN numbers ( i mean i chek the LUN number from vxdisk list output only.....
and also there is some problem with the paths too....
for these 7 extra disks u cn 2 paths instead of 4!!
