Connecting to SAN

UNIX Solaris
1

I am about to attempt to connect my sun 280R boxes to a EMC SAN.
I have Qlogic cards that came from Sun.

I am going to load traffic manager, navisphere client.
what else do i need, sun foundation suite ro somehting?

This is the first time ive ever connected to a SAN.

any help would be appreciated, i have no clue what im doing, LOL..

Thanks

1: You must download SAN foundation kit pkg from sun os EISCD and
SAN Patch from sun or EISCD too.
2 : you install all of pkg and patch
3 : config file sd.conf prepare for new device
4 : use cfgadm for config device and luxadm for check new device

Description:

The objective of this document is providing a general guideline of using luxadm
and cfgadm to check the status of SAN device.

Document Body:

To simplify the sceniario, inter-connected devices (switch or director) will not
be considered in this topic. From the server side, the following items are being
checked :

  1. HBA connection status
  2. LUN connection status

HBA connection status

  • Check /var/adm/message after system boot
    Example:
    Lun=0 for target=41500 disappeared or FCP: target=41500 reported NO Luns
    path /pci@1f,4000/SUNW,qlc@4/fp@0,0 (fp6) to target address:
    50020f2300002a7b,0 is offline

Remark:

  1. status should be "online"
  • luxadm -e port
    Example:
    /devices/pci@1f,4000/SUNW,qlc@4/fp@0,0:devctl CONNECTED
    /devices/pci@1f,4000/SUNW,qlc@4,1/fp@0,0:devctl CONNECTED

Remark:

  1. Dual port HBA should see 2 entries
  2. Status should be "CONNECTED"

LUN connection status

  • cfgadm -al
    Example:
    c5 fc-fabric connected unconfigured unknown
    c5::50020f2300000cab disk connected configured unknown
    c5::50020f2300002a7b disk connected configured unknown

Remark:

  1. Receptacle should be "connected"
  2. Occupant should be "configured"
  • luxadm probe
    Example:
    Node WWN:50020f2000000caa Device Type:Disk device
    Logical Path:/dev/rdsk/c10t60020F2000000CAA3DABB7B10001D2D4d0s2

Remark:

  1. The Universial device name "c10t60020F2000000CAA3DABB7B10001D2D4d0s2"
    is generated based on the WWN of the storage device
  • luxadm disp <path>
    Example:
    luxadm disp /dev/rdsk/c10t60020F2000000CAA3DABB7B10001D2D4d0s2

DEVICE PROPERTIES for disk:
/dev/rdsk/c5t600015D0002109000000000000000104d0s2
Status(Port A): O.K.
Status(Port B): O.K.
Vendor: SUN
Product ID: SE6920
WWN(Node): 230000015d210900
WWN(Port A): 234100015d210900
WWN(Port B): 233100015d210900
Revision: 0201
Serial Num: 08349695
Unformatted capacity: 10240.000 MBytes
Read Cache: Enabled
Minimum prefetch: 0x0
Maximum prefetch: 0xffff
Device Type: Disk device
Path(s):
/dev/rdsk/c5t600015D0002109000000000000000104d0s2
/devices/scsi_vhci/ssd@g600015d0002109000000000000000104:c,raw
Controller /devices/pci@1f,0/pci@1/SUNW,qlc@2/fp@0,0
Device Address 234100015d210900,0
Host controller port WWN 210000e08b0fb16b
Class primary
State ONLINE
Controller /devices/pci@1f,0/pci@1/SUNW,qlc@2,1/fp@0,0
Device Address 233100015d210900,0
Host controller port WWN 210100e08b2fb16b
Class primary
State ONLINE

Remark:

  1. <path> can be found by "luxadm probe"
  2. If there are 2 "Controller" for this device, it is dual path
    connection
  3. If MPxIO is enable, both class of Controller should be "primary",
    and state should be "ONLINE"

To be sure, you have all the necessary drivers and your HW config is suppoorted, check also on www.powerlink.emc.com the ESM --> EMC Support Matrix.

The is also a utility called emc_grab_[OS-Version].tar, run it on the host, and it validates your config.

you can get the SAN Foundation Software base packages from Hardware | Oracle

btw goasutlor, nice tip with the EIS-CD, but that's a sun internal CD, only for employees and partners.....
