  • Lofland bLOG » Adding & Removing Disks on HPUX
    U switch ioscan fnCdisk finds hardware changes and returns NO HW instead of CLAIMED Same thing would happen if anything had tried to read write the disk now use rmsf to revove the dev files for the drive If you ever need to remove a dev file don t use rm use rmsf man is your friend The example here is removing a Hitachi SAN disk ioscan will show you both the hardware address That number with the s and the dev files for the hardware disk 101 0 0 10 0 0 1 0 5 0 10 0 sdisk NO HW DEVICE HITACHI DF600F dev dsk c34t10d0 dev rdsk c34t10d0 To wipe out a piece of hardare run rmsf a dev dsk c0t8d0 The a option should cause this to also remove the dev rdsk file and it shoudln t show up in ioscan funCdisk anymore either Now ioscan will show no signs of the hardware If you don t use the a option then you have to remove both the dev dsk and the dev rdsk files individually Then ioscan will STILL see the drive disk 101 0 0 10 0 0 1 0 5 0 10 0 sdisk NO HW DEVICE HITACHI DF600F So then you must use the hardware address to remove the drive rmsf H 0 0 10 0 0 1 0 5 0 10 0 put disk back in or put in a new disk The replace example here is a local disk the new example is an EMC SAN disk ioscan fnCdisk finds hardware changes and recognizes disk again Devices physically attached to the system should automatically show up when you run ioscan without the u option as above However there are no dev files for things like disks so you can t

  • Lofland bLOG » HPUX ServiceGuard Cluster Manager
    Failback settings If they all say manual then you are in good shape because a package will not move back to its primary node without manual intervention It is possible to use cmmodpkg to tell the packages that they may not move to a given node which would help you in this case See the man page for cmmodpkg Before doing anything crazy you should do a cmviewcl and a cmviewcl v and copy down the info That way you can see how things were set up before When you are done do a cmviewcl v and make sure PKG SWITCH is enabled for all packages It is possible for the cmhaltpkg to disable this on some of them and for you to forget to put it back Here are some tests These should come back with nothing cmviewcl v grep disabled cmviewcl v grep down These should come back with everything cmview v grep enabled cmview v grep up Check to see that everyone is running on their primary server cmviewcl v grep Primary Run cmview v through MORE also and just look to see that it all looks right You should find out from application contact what order the package should go down and up in 99 9 of the time the order does NOT matter Common sense says the come up 1 2 3 and go down 3 2 1 On this box pkgftp can go down anytime and pkg01 05 go down in reverse and up in order cmviewcl CLUSTER STATUS clustername cl5 up NODE STATUS STATE server1 up running PACKAGE STATUS STATE PKG SWITCH NODE pkg01 up running enabled server1 pkg02 up running enabled server1 pkg03 up running enabled server1 pkg04 up running enabled server1 pkg05 up running enabled server1 pkgftp1 up running enabled server1 NODE STATUS STATE server2 up running PACKAGE STATUS STATE PKG SWITCH NODE pkg06 up running enabled server2 pkg07 up running enabled server2 pkg08 up running enabled server2 pkg09 up running enabled server2 pkg10 up running enabled server2 pkgftp2 up running enabled server2 So as root from any member of the cluster I suggest that you do a cmviewcl between these commands periodically to make sure that what you expect to happen is actually happening cmhaltpkg pkgftp1 cmrunpkg n server2 pkgftp1 better to do it this way than just downing the node unless you really feel cool in which case you could technially just do a cmhaltcl server1 and all packages should move over to server 2 automatically See the man page cmhaltpkg pkg05 cmrunpkg n server2 pkg05 cmhaltpkg pkg04 cmrunpkg n server2 pkg04 cmhaltpkg pkg03 cmrunpkg n server2 pkg03 you can t hardly mess up these commands they will complain if you tell it to do the wrong thing cmhaltpkg pkg02 cmrunpkg n server2 pkg02 cmhaltpkg pkg01 cmrunpkg n server2 pkg01 Some boxes can take 30 minutes per package Some boxes take 45 minutes to move stuff over The command will hang there until it is done moving the package
