Create a Soalris 8 zone (32bit) to a container

Last time I had successfully created a flar image from an old Solaris 8 server (ref). Now I have to setup a zone of Solaris 10 container and install the image into it. The overall idea is clear and easy. Normally just create the zone configuration, and install it from a "flar" image.

1. Create zone configuration

root@sol10 # zonecfg -z z_sol8
z_sol8: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:z_sol8> create -t SUNWsolaris8
zonecfg:z_sol8> set zonepath=/pool/zone/sol8
zonecfg:z_sol8> set autoboot=false
zonecfg:z_sol8> set ip-type=shared
zonecfg:z_sol8> add net
zonecfg:z_sol8:net> set address=192.168.123.123
zonecfg:z_sol8:net> set physical=nxge0
zonecfg:z_sol8:net> end
zonecfg:z_sol8> verify
zonecfg:z_sol8> commit
zonecfg:z_sol8> exit


Next install the zone from the flar image:

Failed to exclude directories when running flarcreate on Solaris 8

When I tried to prepare a flash archive (flar) from an old Solaris 8 physical machine, I wanted to exclude two directories (say, /one and /two). I checked the syntax from web (and the man page), it should be:

flarcreate -n -c -S -R / -x /one -x /two
where -c is enable compression, -S is ignore size stats, -R is the root path

However, the directories /one and /two are still in the flar !

After doing some investigation and research from the web, it is believed that there is a bug of this script of the current version. Since it's too old and I don't want to apply any patch on it, I'd rather modify the script a bit in order fulfill my requirement:

Check utilization for Solaris 10

Seems "top" is not available (or not installed by default). Actually there is another command "prstat" which provide similar but more powerful functions:

Change network speed and duplex mode on Solaris 10

When I try to FTP some files using an interface, the speed is unexpectedly slow. Then I try to see the network interfaces status:

root@sunserver # dladm show-dev
nxge0           link: down      speed: 0     Mbps       duplex: unknown
nxge1           link: down      speed: 0     Mbps       duplex: unknown
nxge2           link: unknown   speed: 0     Mbps       duplex: unknown
nxge3           link: unknown   speed: 0     Mbps       duplex: unknown
igb0            link: up        speed: 100   Mbps       duplex: half
igb1            link: unknown   speed: 0     Mbps       duplex: half
igb2            link: up        speed: 100   Mbps       duplex: full
igb3            link: up        speed: 1000  Mbps       duplex: full


Seems 100 Half is a wrong setting. Since the speed is set by auto negotiation mode, we have to change it manually:

First, check the interface properties by "ndd":

Clone a new machine by spliting a miror disk (Vertias VM encapsulated)

Situation: suppose you are going to clone the machine A to machine B

  • Before cloning, make sure the disks are in sync (vxprint -htA, format, etc..)
  • Machine A and Machien B: Shutdown to OK prompt (init 0)
  • Removal of disks should be in OK prompt
  • Insertion of disks can be in OS level

Machine A:

  1. Remove one of the disk and try to boot it with single in OK prompt (boot )

  2. after the OS is up, vxprint should shown the another disk is missing/fault
  3. insert a new disk and issue "vxdctl enable"
  4. vxdiskadm -> 5

  5. resync should be in progress, use "vxtask list" to monitor
  6. Double check (vxprint -htA) and format, if the partition label is not correct, issue "/etc/vx/bin/vxbootsetup (the cxtxdx doesn't work. use 'vxdisk list' to get the disk name first)"

  7. Try to reboot once again

Machine B:

  1. insert the disk of Machine A and boot in OK prompt (boot )

  2. after the OS is up, vxprint should shown the another disk is missing/fault
  3. insert a new disk and issue "vxdctl enable"
  4. vxdiskadm -> 5

  5. resync should be in progress, use "vxtask list" to monitor
  6. Double check (vxprint -htA) and format, if the partition label is not correct, issue "/etc/vx/bin/vxbootsetup (the cxtxdx doesn't work. use 'vxdisk list' to get the disk name first)"

  7. Try to reboot once again

How to add a swap file in Solaris

  1. # mkfile 10m /tmp2/swapfile
  2. # swap -a /tmp2/swapfile
  3. # swap -l
    • swapfile             dev  swaplo blocks   free
      /dev/dsk/c0d0s1 102,1 8 303400 303400
      /dev/dsk/c0d1s6 102,70 8 21160 21160
      /tmp2/swapfile - 8 20472 20472
  4. (Optional, if need to make the change permanent)
    1. Edit /etc/vfstab
              /tmp2/swapfile  -       -       swap    -       no      -
    2. reboot
