Assign the same EMC LUNs to the new server. Recognize all the LUNs in newserver from ioscan. #ioscan -fnKC disk Create a script with the following contents to get the VG info. Here created the script in filename /usr/bin/vgid.# vi /usr/bin/vgidecho ” Disk Name CPU ID PV ID CPU ID VG ID”echo ” ———————————————————“for i […]

In order to successfully move LUNs to a new host, these general steps must be taken.All physical volumes (which relate to a physical LUN) within a volume group must be moved as a group.First backup your /etc/lvmtab and the /etc/fstab files. Under HP-UX on the server where the LUNs currently reside, run the following:      1.

Question: Why does diskinfo on HP-UX return 0 on logical paths connected to a CLARiiON array? Environment: Product: CLARiiON CX-Series Environment: OS: HP-UX Environment: Host Level Protection: PVlinks Problem: ioscan -fnC disk shows both primary and secondary logical paths to the CLARiiON array. Problem: diskinfo reports a value of 0 on the secondary logical paths. Problem:

To create swap, we need a contiguous space on a disk / LUN. Create vg01: pvcreate /dev/rdsk/c12t0d0pvcreate /dev/rdsk/c12t2d0vgcreate -s 8 -p 128 /dev/vg01 /dev/dsk/c12t0d0 /dev/dsk/c12t2d0vgchange -a y /dev/vg01 lvcreate -C y -L 16384 -n lvswap /dev/vg01 /usr/sbin/swapon -f -p 3  /dev/vg01/lvswap add to /etc/fstab: /dev/vg01/lvswap … swap pri=3 0 0 Original post blogged on b2evolution.

To identify processes to kill we need to view the FULL output from the ps command (we use the comm field). But by default we are not able to view full command.  So here is the solution.. Solaris : /usr/ucb/ps -awux You may need two “w” options. From ps(1b): -w Uses a wide output format

When I started in UNIX, I really fancy cheat sheets, as they give quick reference to the most useful commands. They are helpful to both new and experienced administrators. Even the most experienced UNIX system administrators forget their commands, sometimes even the most basic of them. We usually write our commands somewhere, either in a
