unable to uninstall Secure Path

Hi everyone

I have a HPUX 11.11 server which has Secure Path 3.0F installed.

I have to uninstall it as we are migrating to IBM SAN storage, but I get errors when I try to run the swremove command.

I have tried running the command with the SAN disks unmounted (as well as mounted) and always receive the error below.

Any advice is greatly appreciated.

Re: unable to uninstall Secure Path

Hi,


the swjob error clearly say there is an inability to deactivate the VG /dev /dev/vgsgm.

u can try by deactivating that VG manually by using the command as
#vgchange -a n /dev/vgsgm.

check that all the LVs pertaining to that VG and as mounted as filesys have been unmounted.

try by using
#vgdisplay -v /dev/vgsgm

note all the LVs

#bdf

to see all the LVs that are individually mounted.

does this VG also have some LVs that are being used as RAW volumes and that are not mounted as filesystems? u need to check.

#lsof


u can also see if that VG has some contribution made to the system swap as a raw device.

check swapinfo
#swpainfo -tam

if yes remove those swaps from the system.


that is the reason as we need to cjeck first that the VG has anything apart from filesystems that we are missing , specially any RAW devices.


what is the result of running the command
#vgchange -a n /dev/vgsgm

are u able to deactivate the VG?



if these do not work , try to make a vgexport on that VG. But make that u first make an export using -p option in preview mode so that u have a map file that u can use ti import that VG again as reqd.

#vgexport -p -v -s -m /tmp/vgsgm.map /dev/vgsgm.

after this is successful and u have a good and reliable /tmp/vgsgm.map MAP file go on to exactly export that VG from the system using the following command as

#vgexport /dev/vgsgm

then try removing the SecurePath.

I unmount the filesystems above, and when after running the swremove command, they are remounted as part of the CPQswsp checkremove program.

I had previously ran â vgchange â a nâ manually and it works OK.

There are no swap files on that VG.

That particular VG doesnâ t have any raw volumes, but one of the other VGs does (/dev/vgsgm01).

I will try exporting the VG and let you know

Thanks again

Re: unable to uninstall Secure Path

hi


yes but try exporting as i have already said to u

that is forst in the preview mode that is with -p option of the vgexport with -m option so that u can reimport that VG IF reqd.

then when u have a map file then only do a real vgexport as i have said in the earlier post.

Re: unable to uninstall Secure Path

I've been able to get t he software removed by:
manuanly deaactivating VG and then commecting the filesystems out of /etc/fstab.
