Mirroring and FC10 (SureStore)

[Gaetano]

Hi all

I've a K380 server with 2x9GB internal disks and a FC10 external disk system (10 disk slots) with 4x9GB hot swappable disks configured on two different SCSI chains (A and B).
I'd like to install only HPUX10.20 on the first of two internal disks and mirror it on the 2nd one (without extract it while I install core OS on the 1st one), and all applications on the first 2 disks of FC10 and mirror them on the other 2.
SCSI controller A manages all the odd slots (1,3,5,7,9) and B all the even (0,2,4,6,8).
Does someone know the commands to do this by Unix or SAM ?

Many Thanks

Gaetano

Well, if I understand you correctly you are wanting to setup hardware mirroring of your drives across multiple scsi controllers. This is very much possible, but I think that you will need to purchase a license for Mirrordisk/UX. Once it is installed you will then have to come up with a plan for how you want to use the diskspace of the available drives(e.g. new volume group, how many logical volumes, mount points, etc.) Once you have all this info together it is really pretty easy to make happen. The following commands demonstrate how to create the lvol and how to mirror it.

lvcreate -n lvol# vgNEW
/usr/sbin/newfs -F hfs -o largefiles /dev/vgNEW/rlvol#
/usr/sbin/mount -o rw,suid,largefiles,delaylog,datainlog -F hfs /dev/vgNEW/l
vol# /mount_point_dir
lvextend -l 4340 /dev/vgNEW/lvol# /dev/dsk/c#t#d#

This command actually does the mirroring:

lvextend -m 1 /dev/vgNEW/lvol# /dev/dsk/c#t#d#

The last command must be provided the device path for the drive which you wish to mirror to. If I have been unclear about anything, or left something out, someone please correct me or let me know.

Good Luck,
Jason V.
