| The file systems for vPars will differ on two different vPars just as they would differ on two different servers. This means that the disk space con-sumed by two vPars running on one server may very well be twice the disk space consumed by one standard HP-UX running on the same server. Each of the two vPars require their own operating system, applications, user home directories, and so on. This may double your storage requirements since none of the files ystems are shared beyond the NFS file systems that would normally be shared in a networked environment. Let's take a look at the file systems running on two different vPars. The following is a bdf run on the first vPar running on a server (hostname actappd1:) # hostname actappd1 # bdf Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 245760 40769 192184 18% / /dev/vg00/lvol1 111637 74350 26123 74% /stand /dev/vg00/lvol8 1732608 598033 1063751 36% /var /dev/vg00/lvol7 1732608 755560 915987 45% /usr /dev/vg00/u001 1228800 466878 714321 40% /u001 /dev/vg00/lvol4 258048 69857 176476 28% /tmp /dev/vg00/lvol6 1531904 1381306 141226 91% /opt /dev/vg00/lvol5 819200 176005 603031 23% /home # This listing shows vg00, the only volume group configured on the system, and the capacity setup in each logical volume. Next is a bdf run on the second vPar running on a server (hostname ecvpard2:) # hostname actappd1 # bdf Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 143360 43174 93951 31% / /dev/vg00/lvol1 111637 73632 26841 73% /stand /dev/vg00/lvol8 1536000 965183 535326 64% /var /dev/vg00/lvol7 1593344 740643 799434 48% /usr /dev/vg00/lvol4 258048 68619 177641 28% /tmp /dev/vg00/lvol6 2084864 563709 1426107 28% /opt /dev/vg00/lvol5 819200 1314 766771 0% /home # You can see from these two listings that the space consumed by the two vg00 volume groups is roughly twice the space that would be consumed without vPars running. You may very well get twice the work done on this server by running two vPars, so this is probably disk space well spent; however; you need to think about the space being consumed as part of your planning. The first vPar we listed earlier also has several applications running on it. One is Broadvision, which requires its own directory under /opt/bv1to1 as shown in the following listing: # hostname actappd1 # ll /opt total 32 dr-xr-xr-x 7 bin bin 96 Jul 13 15:27 Migration dr-xr-xr-x 9 bin bin 1024 Jul 13 15:26 OV drwxrwxr-x 18 bin bin 1024 Jul 13 15:23 apache dr-xr-xr-x 6 bin bin 96 Jul 13 15:12 asx dr-xr-xr-x 6 bin bin 96 Jul 13 15:24 audio drwxr-xr-x 22 root bin 1024 Sep 21 13:34 bv1to1 drwxr-xr-x 8 root users 1024 Jul 13 15:26 cifsclient dr-xr-xr-x 4 bin bin 96 Jul 13 15:26 cmcluster dr-xr-xr-x 4 bin bin 96 Jul 13 15:25 cmom dr-xr-xr-x 10 bin bin 1024 Jul 13 15:10 dce dr-xr-xr-x 4 bin bin 1024 Jul 13 15:35 dcelocal dr-xr-xr-x 4 bin bin 96 Jul 13 15:13 dmi dr-xr-xr-x 4 bin bin 96 Jul 13 15:11 fcms dr-xr-xr-x 3 bin bin 96 Jul 13 15:17 graphics dr-xr-xr-x 4 bin bin 96 Jul 13 15:08 hparray dr-xr-xr-x 3 bin bin 96 Jul 13 15:14 ifor dr-xr-xr-x 16 bin bin 1024 Jul 19 15:03 ignite dr-xr-xr-x 3 bin bin 96 Jul 13 15:14 image drwxr-xr-x 4 bin bin 96 Jul 13 15:25 java1.2 drwxrwxrwx 7 bin bin 1024 Aug 24 16:34 java1.3 drwxr-xr-x 2 root root 96 Jul 13 15:04 lost+found drwxr-xr-x 7 root sys 96 Aug 24 17:26 make drwxr-xr-x 8 root sys 1024 Jul 13 15:27 mx dr-xr-xr-x 9 bin bin 1024 Jul 13 15:26 netscape dr-xr-xr-x 7 bin bin 96 Jul 13 15:09 nettladm dr-xr-xr-x 2 bin bin 96 Jul 13 15:11 networkdocs dr-xr-xr-x 4 bin bin 96 Jul 13 15:16 parmgr dr-xr-xr-x 7 bin bin 96 Jul 13 15:13 pd dr-xr-xr-x 12 root bin 1024 Jul 13 15:25 perf dr-xr-xr-x 9 bin bin 1024 Jul 13 15:26 prm dr-xr-xr-x 4 bin bin 96 Jul 13 15:11 raid4si dr-xr-xr-x 6 bin bin 96 Jul 13 15:12 resmon drwxr-xr-x 10 root users 1024 Jul 13 15:25 samba drwxr-xr-x 3 root users 96 Jul 13 15:24 samba_src dr-xr-xr-x 8 bin bin 1024 Jul 13 15:16 scr drwxr-xr-x 3 root bin 96 Aug 24 13:42 tivoli drwxrwxr-x 11 bin bin 1024 Jul 13 15:24 tomcat dr-xr-xr-x 5 bin bin 96 Jul 13 15:10 upgrade dr-xr-xr-x 4 bin bin 96 Jul 13 15:25 video dr-xr-xr-x 6 bin bin 96 Jul 13 15:26 webadmin drwxr-xr-x 10 bin bin 1024 Jul 13 15:27 wlm # The bv1to1 directory is the directory in which the Broadvision application is loaded.

Maintaining additional HP-UX file systems, which is probably going to be the case when you run vPars, requires you to think about the additional disk space required as well as techniques to ensure that your systems run smoothly such as recovery and operating system and application updates. Be sure to have a current inventory of your systems and perform backups and create bootable recovery tapes often. |
