- Gaurav_SModeratorFirstly you will need to label those disks using "format" utility of solaris...
# format
<select disk>
disk> label
command to initialize disk in veritas would be
# vxdisksetup -i c3t500601643CE00BB6d186 format=sliced
repeat the same step for lun 186 to 195 ....
To add them into a diskgroup (please note, below mentioned is a single command, copy paste in a notepad first & then run on server)
# vxdg init dg_vx1 dg_vx1_00=c3t500601643CE00BB6d186s2 dg_vx1_01=c3t500601643CE00BB6d187 dg_vx1_02=c3t500601643CE00BB6d188 dg_vx1_03=c3t500601643CE00BB6d189 dg_vx1_04=c3t500601643CE00BB6d190 dg_vx1_05=c3t500601643CE00BB6d191 dg_vx1_06=c3t500601643CE00BB6d192 dg_vx1_07=c3t500601643CE00BB6d193 dg_vx1_08=c3t500601643CE00BB6d194 dg_vx1_09=c3t500601643CE00BB6d195
you can check your vxdisk list now... it should show same output...

You can use vxdiskadm ( option 1 ) to initialize multiple disks and add them in diskgroup.
Please check below example of adding 4 new disks.
# vxdiskadm

Select an operation to perform: 1
Add or initialize disks
Menu: VolumeManager/Disk/AddDisks
Use this operation to add one or more disks to a disk group. You can
add the selected disks to an existing disk group or to a new disk group
that will be created as a part of the operation. The selected disks may
also be added to a disk group as spares. Or they may be added as
nohotuses to be excluded from hot-relocation use. The selected
disks may also be initialized without adding them to a disk group
leaving the disks available for use as replacement disks.
More than one disk or pattern may be entered at the prompt. Here are
some disk selection examples:
all: all disks
c3 c4t2: all disks on both controller 3 and controller 4, target 2
c3t4d2: a single disk (in the c#t#d# naming scheme)
xyz_0 : a single disk (in the enclosure based naming scheme)
xyz_ : all disks on the enclosure whose name is xyz

You can choose to add these disks to an existing disk group, a
new disk group, or you can leave these disks available for use
by future add or replacement operations. To create a new disk
group, select a disk group name that does not yet exist. To
leave the disks available for future use, specify a disk group
name of "none".

Sorry Stefan. Forgot to mention in last post that you have to label disks using format utility and rescan the the disks in vxvm using "vxdctl enable"
Regards, - stefanhanseLevel 3
Many thanks to all. At the moment I have a problem to label the disks itself, maybe the LUNS sharing needs some improvements.
If I try to initialise the first disk I got the following error /etc/vx/bin/vxdisksetup -i c3t500601643CE00BB6d196 format=sliced
prtvtoc: /dev/vx/rdmp/c3t500601643CE00BB6d196s2: Unable to read Disk geometry errno = 0x6
Kind regards Stefan - g_leeLevel 6As Gaurav and Anoop both stated above, you need to label the disks with format before running vxdisksetup - if they do not have a label, VxVM will not be able to set them up.
eg:
# format c3t500601643CE00BB6d196
> label
Ready to label (y/n): y
> quit
# prtvtoc /dev/rdsk/c3t500601643CE00BB6d196s2
^^^^^ this command should show a partition table. If it does, then proceed with vxdisksetup. If it doesn't, you need to rerun the label in format / investigate why format hasn't labelled the disk
- Gaurav_SModerator
Are you facing any error while labeling the disk using format utility? If yes, can u paste the error ?
Gaurav - stefanhanseLevel 3
The problem is that I have 10 LUNs mulipathing over 4 HBA an I have a problem to easyly found the active path that LUN that I have to configure!
Is the a way to easyly display which path is active an which is passive? - g_leeLevel 6Stefan,
You haven't mentioned the type of array you are using, so it's hard to provide detailed instructions for how to display the active path.
Depending on the type of array you are using, you could see if vxdisk list displays the status of the paths, eg:
Multipathing information:
numpaths: 4
cXtXXXXXXXXXXXXXXXXXdXs2 state=enabled type=secondary
cXtXXXXXXXXXXXXXXXXXdXs2 state=enabled type=primary
cXtXXXXXXXXXXXXXXXXXdXs2 state=enabled type=primary
cXtXXXXXXXXXXXXXXXXXdXs2 state=enabled type=secondary
If it does display this, then pick one of the primary paths to label the disk ie: format cXtXXXXXXXXXXXXXXXXXdX
Note however that vxdisk may not display this as the disks don't have a label yet.
Unless the array trespasses when you access the passive path, then at this point it probably doesn't matter, provided you can access the disk to label it and carry on with the setup - stefanhanseLevel 3
Hello, I have found a way to display the needed informations, now I can easyly label the right LUNs,
for the next step I have to select the "correct" LUNS with the vxdisksetup command.
