I tried export/import.

The disks are mapped through VSCSI.

I will make a test, unmapping the disks, running cfgdev on VIOS and then remapping them.

Thanks!

Hello!

This procedure works:

1.- Stop PowerHA services in both nodes.

2.- In VIOS A:
$ rmdev -dev vtd_data_A
$ rmdev -dev vtd_data_B
$ r oem
# rmdev -dl hdisk1
# rmdev -dl hdisk2
# cfgmgr
# chdev -l hdisk1 -a reserve_policy=no_reserve
# chdev -l hdisk2 -a reserve_policy=no_reserve
# exit
$ mkvdev -vdev hdisk1 -vadaper vhost0 -dev vtd_data_A
$ mkvdev -vdev hdisk2 -vadaper vhost0 -dev vtd_data_B


3.- Repeat step 2 en VIOS B.

4.- On node A:
# rmdev -dl hdisk3
# rmdev -dl hdisk4
# cfgmgr
# chdev -l hdisk3 -a reserve_policy=no_reserve
# chdev -l hdisk4 -a reserve_policy=no_reserve
# chdev -l hdisk3 -a queue_depth=10
# chdev -l hdisk4 -a queue_depth=10
# varyonvg vg_data
0516-1434 varyonvg: Following physical volumes appear to be grown in size.
Run chvg command to activate the new space.
hdisk3 hdisk4
# chvg -g vg_data
# varyoffvg vg_data

5.- Repeat step 4 on node B, except chvg -g.


Thanks for the support!

This is why I asked if they were mapped as VSCSI as the new disks needed re-mapping.

NAME
cfgmgr - Configuration management server SYNOPSIS
/sbin/cfgmgr DESCRIPTION
The cfgmgr configuration management server works with the kernel load server (kloadsrv) daemon to manage the subsystems that are dynami- cally configurable, loadable, or both. The cfgmgr server starts up automatically when a client (such as the sysconfig command) makes a con- figuration management request. Examples of configuration management requests are requests to configure, reconfigure, query, or unconfig- ure a subsystem. The cfgmgr server allows query operations from any superuser (root login), local or remote. The superuser on the local system is also allowed to configure, reconfigure, or unconfigure local kernel subsystems. Remote access to the kernel subsystem configuration is allowed through the /etc/cfgmgr.auth file. System administrators working on hosts listed in that file can also configure, reconfigure, or uncon- figure local kernel subsystems. If the /etc/cfgmgr.auth file does not exist or is empty, no remote users are allowed to configure, recon- figure, or unconfigure local kernel subsystems. If you use the sysconfig -v command, the cfgmgr server displays debugging information to the /dev/console screen. See the sysconfig(8) ref- erence page for more information about the -v flag.
