Identify PV device in HP-UX 11.31

Lincoln Zuljewic Silva — Thu, 08 Sep 2011 18:44:30 +0000

In HP-UX 11.31, LVM doesn’t use “ctd’ (ie: /dev/rdsk/c2t1d0), but DSF to balance the throughput between many device paths., so if you need identify what physical device represent that logical device, you can use ioscan, for example:
server@root:/root # vgdisplay -v vg00 --- Volume groups --- VG Name                     /dev/vg00 VG Write Access             read/write VG Status                   available Max LV                      255 Cur LV                      12 Open LV                     12 Max PV                      16 Cur PV                      1 Act PV                      1 Max PE per PV               4385 VGDA                        2 PE Size (Mbytes)            16 Total PE                    4375 Alloc PE                    3998 Free PE                     377 Total PVG                   0 Total Spare PVs             0 Total Spare PVs in use      0 VG Version                  1.0 VG Max Size                 1122560m VG Max Extents              70160

Note that the pv name is “disk4”, not c2t1d3.

With ioscan you can reverse map it:
server@root:/root # ioscan -m dsf Persistent DSF Legacy DSF(s) ======================================== /dev/rdisk/disk3 /dev/rdsk/c2t1d0 /dev/rdisk/disk4 /dev/rdsk/c2t0d0 /dev/rdisk/disk5 /dev/rdsk/c0t0d0

Now we know that the “disk4″ is the physical disk located in 12/0/1/1/0.0.0
root@brux0044:/root # ioscan -fnC disk Class I H/W Path Driver S/W State H/W Type Description ======================================================================== disk 1298 12/0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 73.4GMAP3735NC /dev/dsk/c2t0d0 /dev/rdsk/c2t0d0

Merge many depots

Lincoln Zuljewic Silva — Tue, 25 Aug 2009 17:58:23 +0000

When you have many depot files, you can create a single big depot and install it instead of install one by one. Let’s assume that you need install the following depots, and they are all located in the directory /tmp/install/depots:

autoconf-2.64-hppa-11.11.depot bison-2.4.1-hppa-11.11.depot gawk-3.1.7-hppa-11.11.depot sed-4.2.1-hppa-11.11.depot tcltk-8.5.7-hppa-11.11.depot texinfo-4.13-hppa-11.11.depot zip-3.0-hppa-11.11.depot

To create a single depot, run the follow commands:
# cd /tmp/install/ for i in `ls depots/*.depot` ;do swcopy -s /tmp/install/$i \* @/tmp/install/big;done

Now, to install it, you can use:
# swinstall -s /tmp/install/big
