remove fs, lv, vg ...

[Tomas Helsén_1]

Hi,

We are running HPUX 11iv2 on Itanium rx4640, the file system is created with disk from EVA 3000

I'm removing a filesystem that are not in use by performing this steps..

1. sam
remove filesystem

2. from commandline
# lvremove -f /dev/vg11/lvol11

3. from commandline
# vgchange -a n /dev/vg11

4. from commandline
# vgexport /dev/vg11

5. In EVAmgr i unpresent the Vdisk.

6. from commandline
rmsf -H 255/255/0/0.6


Status after this is
disk 9 255/255/0/0.6 sdisk NO_HW DEVICE HSV100 HP

How do I remove this entry? do I have to reboot the system?

Hi,

If ur intention is to remove the file system
then

# lvremove -f is sufficient,

it will also remove device files for corresponding LVs.

but if u want to get rid of

disk 9 255/255/0/0.6 sdisk NO_HW DEVICE HSV100 HP

this line , then u have to reboot the system,
but is it so important to get rid of that line?

Tomas,

Are you running securepath on your servers?

If yes

spmr display (check for device removed lun)

spmgr delete cxtydz

ioscan -fnC disk
insf -e
ioscan -funC disk

OK spmgr display gives this..
TGT/LUN Device WWLUN_ID H/W_Path #_Paths
