MC-ServiceGuard on HP-J2240

[Jack Fan]

All,
Could able to install MC-ServiceGuard on HP-J2240?
And I have two HP-J2240 connect to one third party diskarray but I encounter vgchange problem, I export VG from HP-J2240 via command vgexport -v -s -p -m /tmp/vg02.map vg02 , then import to alternative HP-J2240 via command vgimport -v -s -m /tmp/vg02.map vg02 and it is complete without error, but system appear error message when I issue command vgchange -a y vg02

vgchange: Couldn't activate volume group "vg02":
Invalid argument

I don't know what's happend.

Hello

You will have to deactivate Volume group from the system where you did vgexport.

Volume group can only activate in one system at a time.

machine1
#vgchange -a n /dev/vg02
manchune2
#vgchange -a y /dev/vg02

Have you done a vgchange -c y? If so, you must do a vgchange -a e to activate the VG in exclusive mode. Having said this, you should be aware that MC/SG is not supported on workstations. You may get it to work but it is often not reliable.

Hi Jack,

The MC/SG is only supported in 800 series systems ( servers) and not in 700 series ( workstations). As you have a J Class workstation, you may find difficulty doing this.

But you can try activating VG by :

# vgchange -a e /dev/vg01 ( provided the cluster service is installed )

HTH,

The error message still occurred even I issue command vgchange -a e vg02.

MC/Serviceguard is not supported on ANY workstation model.

As for the vgchange error, have you deactivated the vg on the other node?

First, HP will not support clusters running on 700 series systems (workstations) but it can be done. Second, you must make the volume group rights into exclusive mode:

vgchange -a -e (exclusive mode).
