If something changes ...
(eg: LUN -> Host mapping) it might be possible to execute reboot -- -r twice.
After the first reboot sometimes no volume is visible
If after second reboot no device is visible it might be necessary to remove /etc/symsm/mnf. The output of /usr/lib/symsm/bin/hot_add will indicat that.
After changing the the Family Set Field in /etc/opt/SUNWsamfs/mcf it is necessary to run samfsck -R -F <volume name>
the Equipment Ordinal Field in /etc/opt/SUNWsamfs/mcf should be uniq ... at least in the future
Add new host to storage array
- add WWN's to db (
hbainvent) - create host script:
mksanhostscr <host> > <host>.scr SMcli sevenofnine -p <passwd> -f <host>.scrSMcli threeofnine -p <passwd> -f <host>.scr
Howto change to mirror volume
- change the role of the volume (SMclient)
- check for correct host lun maping (access for mirror volume, no access for the old volume)
- disable entries in /etc/vfstab on affected hosts
# reboot -- -r- check for new device name and change in /etc/vfstab and /etc/opt/SUNWsamfs/mcf
# samd config# reboot

Starting from scratch
- on every console (serial) enter
sysWipe - this destoys anything immediately but net config and Premium Features will not be lost.
Now you have a storage virgin. - net config can be viewed with
netCfgShowand changed withnetCfgSet - add all devices (controller) to Management Console and rename them.
- apply host lists
SMcli <storage device> -f /home/admin/san/createhosts.scr - change tray order (not as important)
- enable media scan
- enable RVM on both storage systems
- define hot spares
Misc
/usr/local/bin/sanmonitor on reload collects switch throughput and storage profiles ... not essential but useful
