Solaris 9 Scan for New SAN Luns & and Vertias Volume Manager Quick Start

Radar1Today we are going to take a little trip into the past and learn about how to add disks to Solaris 9, put them under Veritas control, and, create a volume group and a volume. This information will come in very handy if you acidentally time travel back 10 years and are forced to get a job as a UNIX Admin.

First off note that you may not need to run the command shown directly below, as Solaris may actually see the disks without performing a lip. This was not the case for me so I needed to perform a lip on each path. First I needed to find my paths as shown below.

# luxadm -e port

Found path to 2 HBA ports

/devices/pci@1d,700000/SUNW,qlc@1/fp@0,0:devctl                    CONNECTED/devices/pci@1d,700000/SUNW,qlc@1,1/fp@0,0:devctl                  CONNECTED

Then I forcelip'd each port.

# luxadm -e forcelip /devices/pci@1d,700000/SUNW,qlc@1/fp@0,0:devctl

# luxadm -e forcelip /devices/pci@1d,700000/SUNW,qlc@1,1/fp@0,0:devctl

Then run the configuration command to find your new disks. My new luns are the ones that are unconfigured.

# cfgadm -o show_FCP_dev -alAp_Id                          Type         Receptacle   Occupant     Conditionc3                             fc-fabric    connected    configured   unknownc3::50000972085ea995           disk         connected    unconfigured unknownc3::50060e8005be5830,0         disk         connected    configured   unknownc3::50060e8005be5830,1         disk         connected    configured   unknownc4                             fc-fabric    connected    configured   unknownc4::50000972085ea990           disk         connected    unconfigured unknownc4::50060e8005be5820,0         disk         connected    configured   unknownc4::50060e8005be5820,1         disk         connected    configured   unknown

Now lets configure the two disks so that we can use them

# cfgadm -c configure c3::50000972085ea99# cfgadm -c configure c4::50000972085ea9905

Now Vertias should see the disks, so lets check.

# vxdisk -e -o alldgs listDEVICE       TYPE           DISK        GROUP        STATUS               OS_NATIVE_NAME   ATTR        disk_4       auto:none      -            -           online invalid       c1t0d0s2         -                   -            disk_7       auto:none      -            -           online invalid       c1t1d0s2         -            emc0_061a    auto           -            -           nolabel              c3t50000972085EA995d5s2 tdev         emc0_061b    auto           -            -           nolabel              c3t50000972085EA995d6s2 tdev         emc0_061c    auto           -            -           nolabel              c3t50000972085EA995d7s2 tdev         emc0_061d    auto           -            -           nolabel              c3t50000972085EA995d8s2 tdev         emc0_061e    auto           -            -           nolabel              c3t50000972085EA995d9s2 tdev         emc0_0616    auto           -            -           nolabel              c3t50000972085EA995d1s2 tdev         emc0_0617    auto           -            -           nolabel              c3t50000972085EA995d2s2 tdev         emc0_0618    auto           -            -           nolabel              c3t50000972085EA995d3s2 tdev         emc0_0619    auto           -            -           nolabel              c3t50000972085EA995d4s2 tdev   

Each lun that's presented above will be used for a specific filesystem/mount. In this specific instance I was given these two lun ids for a new mount 061D,061E. The rest will be used later to mirror existing mounts.

Now lets label these two luns. Using the information above from the vxdisk output, I grab the OS_NATIVE_NAME and use that for the format command.

# format c3t50000972085EA995d8s2 c3t50000972085EA995d9s2

Note how the format command prompts me to label the disks before I can format them. Note that I am not going to format them, just label them.

AVAILABLE DISK SELECTIONS:       0. c3t50000972085EA995d8s2 <EMC-SYMMETRIX-5874 cyl 54612 alt 2 hd 15 sec 128>          /pci@1d,700000/SUNW,qlc@1/fp@0,0/ssd@w50000972085ea995,8       1. c3t50000972085EA995d9s2 <EMC-SYMMETRIX-5874 cyl 54612 alt 2 hd 15 sec 128>          /pci@1d,700000/SUNW,qlc@1/fp@0,0/ssd@w50000972085ea995,9Specify disk (enter its number)[0]: 1selecting c3t50000972085EA995d9s2[disk formatted]Disk not labeled.  Label it now? yesformat> quit

Now use vxdisksetup, option one to initialize the luns. Excerpt below.

Select disk devices to add: [<pattern-list>,all,list,q,?] emc0_061d emc0_061e  Here are the disks selected.  Output format: [Device_Name]  emc0_061d emc0_061e

Now lets create our diskgroup – this one I shall call FDEV2_dg.  Note that the format below creates the disk group adds two disks to it. We are also giving each disk an "alias".

# vxdg init FDEV2_dg FDEV2_dg_d0=emc0_061d  FDEV2_dg_d1=emc0_061e

Now lets create a volume. This volume will me 99g

# vxassist -g FDEV2_dg make FDEV2_dg_v1 99g layout=stripe

Ok almost done – lets now slap a file system on that sucka.

# mkfs -F vxfs /dev/vx/rdsk/FDEV2_dg/FDEV2_dg_v1

Now lets the line below to /etc/vfstab.

/dev/vx/dsk/FDEV2_dg/FDEV2_dg_v1 /dev/vx/rdsk/FDEV2_dg/FDEV2_dg_v1 /u06  vxfs 2 yes suid

And lets mount it.

# mount /u06
