Migration of Stand Alone SCSI Data to Virtual SCSI Data _ IBM AIX Part I

The below process shows the migration of data from a Standalone SCSI Disk to a LPAR Managed by a VIOS.

Step 1 on AIX_Server:

1) Identify the disk that has to be moved to the LPAR.

# lspv

hdisk0 002631cd31ad04f5 rootvg

active

2) Check the disk to be migrated have a unique UDID.

# lsattr  -EHL hdisk0

PCM PCM/friend/scsiscsd Path Control Module

False

algorithm fail_over Algorithm

True

dist_err_pcnt 0 Distributed Error Percentage

True

dist_tw_width 50 Distributed Error Sample Time

True

hcheck_interval 0 Health Check Interval

True

hcheck_mode nonactive Health Check Mode

True

max_transfer 0x40000 Maximum TRANSFER Size

True

pvid 002631cd31ad04f5

False

queue_depth 3 Queue DEPTH

False

reserve_policy single_path Reserve Policy

True

size_in_mb 146800 Size in Megabytes

False

0000000000000000 Physical volume identifier

unique_id 22080004B9710BST3146807LC03IBMscsi

False

3) Identify the parent of the hdisk0

# lsdev -Cl hdisk0 -F parent

scsi1

# lsdev -l scsi1 -F parent

sisscsia0

So the hdisk0 is attached to the scsi1 which has the parent sisscsia0.

4) Next step is to identify any the resources attached to the same sisscsia0.

# lsdev | grep -i siscsia0
sisscsia0 Available 00-08 PCI-X Dual Channel Ultra320 SCSI Adapter

# lsdev | grep "00-08"

hdisk0 Available 00-08-01-1,0 16 Bit LVD SCSI Disk Drive

scsi0 Available 00-08-00 PCI-X Dual Channel Ultra320 SCSI Adapter bus

scsi1 Available 00-08-01 PCI-X Dual Channel Ultra320 SCSI Adapter bus

ses0 Available 00-08-00-14,0 SCSI Enclosure Services Device

ses1 Available 00-08-00-15,0 SCSI Enclosure Services Device

ses2 Available 00-08-01-14,0 SCSI Enclosure Services Device

ses3 Available 00-08-01-15,0 SCSI Enclosure Services Device

sisscsia0 Available 00-08 PCI-X Dual Channel Ultra320 SCSI Adapter

So only one hdisk is allocated to the sisscsia0.

5) Obtain the hardware location code of the drive.

# lscf g -vpl siscsia0

sisscsia0 U78A0.001.0000000-P1-C4 PCI-X Dual Channel Ultra320 SCSI

Adapter

PCI-X Dual Channel Ultra320 SCSI Adapter:

Part Number.................97P3359

FRU Number..................97P3359Hardware Location Code......U78A0.001.0000000-P1-C4

6) Shutdown the AIX_Server with the shutdown command.
