creatng a logical volume

Jeff Hagstrom — Fri, 22 Aug 2008 11:48:17 GMT

I'm creating a logical volume, however the Use column says unused with no mount directory? Why won't it create the volume?

Hi Jeff:

What exactly are you doing? What command are you using? What is the "use column"?

> Why won't it create the volume?

What error message do you get?

Regards!

I have an RP7410 running 11.11 and I need to add a new logical volume called vg01-u13 mounted to /u13 vg01-u14 mounted to u14. I am using SAM to add the volume group.

mkdir /u13
mkdir /u14
lvcreate -L size -n u13 /dev/vg01
newfs -F vxfs -o largefiles /dev/vg01/ru13
mount -f vxfs /dev/vg01/u13 /u13
make the entry in /etc/fstab

similar steps to u14

Thanks

change the xxxx into the size in MB

This is the message/error that comes out after creating the LG.

The command used to remove a logical volume, /sbin/lvremove, has failed.
The stderr output from the command is shown below.

The logical volume has not been removed.

Looks like you have a failed disk.

Check

# ioscan -fn

for /dev/dsk/c6t0d0.

Hi,

first check the
1) ioscan -fnC disk |grep c6t0d0

2) check whether pv is a part of vg01
vgdislpay -v vg01 |grep c6t0d0

Hi Jeff,

provide following

#vgdisplay -v vg01

Also

#vgcfgrestore -v -l vg01

Regarding disk you run ioscan and verify if you can see disk in ioscan o/p

pvdisplay diskname
