How to create destroy and increase a zpool

1.-Is very important to have the LUN's allocated in the server and discover them, the first step is check what are the controller associated to the SAN boxes

unavailable scsi-sas     n        /devices/pci@0,600000/pci@0/pci@8/pci@0/scsi@1:scsi
c0::dsk/c0t0d0                 connected    configured   unknown    SEAGATE ST914603SSUN146G
unavailable disk         n        /devices/pci@0,600000/pci@0/pci@8/pci@0/scsi@1:scsi::dsk/c0t0d0

unavailable fc-fabric    n        /devices/pci@0,600000/pci@0/pci@9/SUNW,qlc@0/fp@0,0:fc
c1::500601601111111f           connected    configured   unknown
unavailable disk         n        /devices/pci@0,600000/pci@0/pci@9/SUNW,qlc@0/fp@0,0:fc::500601604460160f
c1::500601681111111f           connected    configured   unknown
unavailable disk         n        /devices/pci@0,600000/pci@0/pci@9/SUNW,qlc@0/fp@0,0:fc::500601684460160f
c2                             connected    unconfigured unknown
unavailable fc           n        /devices/pci@0,600000/pci@0/pci@9/SUNW,qlc@0,1/fp@0,0:fc
c3                             connected    configured   unknown
unavailable fc-fabric    n        /devices/pci@2,600000/SUNW,qlc@0/fp@0,0:fc
c3::500601614111111f           connected    configured   unknown
unavailable disk         n        /devices/pci@2,600000/SUNW,qlc@0/fp@0,0:fc::500601614460160f

unavailable disk         n        /devices/pci@2,600000/SUNW,qlc@0/fp@0,0:fc::500601694460160f
c4                             connected    unconfigured unknown

Example:
#devfsadm
or if you want using the command above "cfgadm -avl"
#cfgadm -c configure c1
#cfgadm -c configure c3

2.-You can check that the new devices are present

#ls -ltr | grep "Aug 19"
lrwxrwxrwx   1 root     root          67 Aug 19 2014 c5t6006016044412200F8DC3222D281E311d0s2 -> ../../devices/scsi_vhci/ssd@g6006016005512200f8dc2222d281e311:c,raw
lrwxrwxrwx   1 root     root          67 Aug 19 2014 c5t600601604441220012E28033367CE311d0s2 -> ../../devices/scsi_vhci/ssd@g600601600551220012e28033367ce311:c,raw
3.-You will need to label the Lun's
#format -e c5t6006016044412200F8DC3222D281E311d0s2
FORMAT MENU:
        disk       - select a disk
        type       - select (define) a disk type
        partition - select (define) a partition table
        current    - describe the current disk
        format     - format and analyze the disk
        repair     - repair a defective sector
        label      - write label to the disk
        analyze    - surface analysis
        defect     - defect list management
        backup     - search for backup labels
        verify     - read and display labels
        inquiry    - show vendor, product and revision
        scsi       - independent SCSI mode selects
        cache      - enable, disable or query SCSI disk cache
        volname    - set 8-character volume name
        !<cmd>     - execute <cmd>, then return
        quit
format> label
[0] SMI Label
[1] EFI Label
Specify Label type[1]: 0
format> q
The same for the other one

1.-Create a Zpool called "zpmysql"

#zpool create zpmysql c5t6006016044412200F8DC3222D281E311d0
2.-Validate the pool creation
# zpool list
NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
zpmysql 14G 31k 30G 0% ONLINE -

3.-If you need to increase the pool you can add one disk in this case we have other disk assigned with "30G"

"c5t600601604441220012E28033367CE311d0s2"
#zpool add zpmysql c5t600601604441220012E28033367CE311d0
# zpool list
NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
zpmysql 30G 31k 30G 0% ONLINE -

4.-Destroy the zpool in order to decomm the disk or if you migrated to another server or disk

#zpool destroy zpmysql

How to Reset the Root Password of RHEL-7 / systemd

1) Boot your system and wait until the GRUB2 menu appears. 2) In the boot loader menu, highlight any entry and press e . 3) Find the line beginning with linux. At the end of this line, append the following: init=/bin/sh Or if you face a panic, instead of "ro" change to "rw" to sysroot as example below: rw init=/sysroot/bin/sh 4) Press F10 or Ctrl+X to boot the system using the options you just edited. Once the system boots, you will be presented with a shell prompt without having to enter any user name or password: sh-4.2# 5) Load the installed SELinux policy: sh-4.2# /usr/sbin/load_policy -i 6) Execute the following command to remount your root partition: sh4.2# mount -o remount,rw / 7) Reset the root password: Raw sh4.2# passwd root 9) Reboot the system. From now on, you will be able to log in as the root user using the new password set up during this procedure.
