Environment IBM DS8K + SAN192 + Redhat6.1+Multipath software

It is divided into three steps: first zone, then storage, and finally multi-path binding on the host side.

one。 Zone

In order to back up the tsm later, zone both the POS and DS8700,TS3500 of the mobile phone, and in order to ensure the safety of production, the two switches are marked zone respectively.

1. Connect to the SAN384 switch and back up the original config

The native IP is set to 10.77.77.88 Universe 255.255.255.0

@ linlf One by one

two。 Create a group in DS8700 based on the wwid number of the host HBA card of the mobile phone pos, and the newly drawn lun is mapped to this group.

(1) Log in to DS8700

The ip of the two controllers is 172.16.0.3 and 172.17.0.4 respectively.

The host ip connects to the DS8700 array through automatic DHCP, and then finds the array management IP for login below (ping 172.17.0.4)

Enter the console with the client software, and then enter the command > dscli, which will pop up

Dscli >

C:\ Program Files\ IBM\ dscli > dscli

Enter the primary management console IP address:172.17.0.4

User name: admin password: xxx

(2) establish volumegroup

Mkvolgrp-type scsimap256 mpos

-- reverse operation: rmvolgrp v9

Query the newly created volume group

Dscli > lsvolgrp

The ID of the new volume group should be v9

(3) lun

A total of 5 200g lun,4 and 5G lun need to be delimited (which extpool is divided to be determined)

DS8700 has a total of 8 extent pool of P0murP7

The remaining space is as follows:

Name ID stgtype rankgrp status availstor (2 ^ 30B)% allocated available reserved numvols

=

Ext_P0 P0 fb 0 below 1199 62 1199 0 14

Ext_P1 P1 fb 1 below 1199 62 1199 0 14

Ext_P2 P2 fb 0 below 1199 62 1199 0 14

Ext_P3 P3 fb 1 below 1149 64 1149 0 24

Ext_P4 P4 fb 0 below 1732 53 1732 0 14

Ext_P5 P5 fb 1 below 1732 53 1732 0 14

Ext_P6 P6 fb 0 below 1732 53 1732 0 14

Ext_P7 P7 fb 1 below 1732 53 1732 0 14

According to the principle of decentralized IO, draw a 200G lun from P3-P7 and a 5G lun from P4-P7.

According to the previous naming rules and the order of the vol

Mkfbvol-extpool P3-cap 200-name vol_#h 1321

Mkfbvol-extpool P4-cap 200-name vol_#h 1417

Mkfbvol-extpool P5-cap 200-name vol_#h 1514

Mkfbvol-extpool P6-cap 200-name vol_#h 1614

Mkfbvol-extpool P7-cap 200-name vol_#h 1714

Mkfbvol-extpool P4-cap 5-name vol_#h 1418

Mkfbvol-extpool P5-cap 5-name vol_#h 1515

Mkfbvol-extpool P6-cap 5-name vol_#h 1615

Mkfbvol-extpool P7-cap 5-name vol_#h 1715

-- reverse operation: rmfbvol-safe 1321

Rmfbvol-safe 1417

Rmfbvol-safe 1514

Rmfbvol-safe 1614

Rmfbvol-safe 1714

Rmfbvol-safe 1418

Rmfbvol-safe 1515

Rmfbvol-safe 1615

Rmfbvol-safe 1715

In the POOL of P3-P7, there are five 200G lun in total.

In the POOL of P4-P7, four 5G lun are divided into 1418, 1515, 1615 and 1715 lun.

(4) Map lun to group of the host

Chvolgrp-action add-volume 1321, 1417, 1514, 1614, 1714, 141815, 1515, 1615, 1715 v9.

-- reverse operation: chvolgrp-action remove-volume 1321 141414141414141414151515151515v9

Create an Map connection between the array and the host.

-- reverse operation: lshostconnect-volgrp v9 to get host_connect_id

three。 Bind multipath

1. Install multipath and generate / etc/multipath.conf file

# fdisk-l | grep sd checks the hard disk. For linux, you can't see the new storage device, so you need to restart the host.

Use scsi_id-g-u to check the wwid number of the newly drawn lun

# yum install device-mapper-multipath.x86_64

Generate multipath.conf file

# cp / usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf / etc/multipath.conf

two。 Configuration / etc/multipath.conf file

Configure the / etc/multipath.conf file according to the queried wwid number and edit it according to the / etc/multipath.conf file of other hosts on the production

Blacklist_exceptions {

Devnode "^ (sd) [bmurz]"

Devnode "^ (dm-) [0-9]"

}

Defaults {

User_friendly_names yes

}

}

After configuration / etc/multipath.conf

# / etc/init.d/multipathd start

# multipath-ll command queries the multipath disk and restarts the server to make sure the server is OK

# ll / dev/mapper/ to view the multipath disk under this path

The disk bare device is bound, and the database installation is completed by the integrator.
