AIX booting from the HP SVSP (boot from SAN)
1. Before upgrading to the new TL/ML, remove all redundant paths and keep only one path to
the SVSP disks. To identify the paths of the disk, execute following command:
# lspath –l hdisk3
NOTE: You may have to change the host's SVSP zoning.
2. Remove all SVSP disks except the boot disk. For example:
rmdev –dRl hdisk3
To identify the SVSP disk, check the properties of the disk and look for the “node_name”
property which should show the WWN of the SVSP array. For example:
# lsattr -El hdisk3|grep node_name
node_name 0x50011fe12a56ac00 FC Node Name False
To identify boot disk, execute the following command:
#bootlist –m normal -o
3. Install the TL/ML (follow instructions provided by IBM).
4. Reboot the server.
5. If other SVSP disks (non-boot LUNs) were discovered again, remove the disks using the rmdev
command (see step 2).
6. Uninstall the SVSP MPIO from the system. For example:
# installp –u devices.fcp.disk.HP.svsp.mpio.rte
Verify that it has been uninstalled properly. For example:
# lslpp -l devices.fcp.disk.HP.svsp.mpio.rt
The above command should return no output.
NOTE: Do not reboot the server.
7. Install the HP SVSP MPIO kit. For installation instruction, refer to the AIX SVSP MPIO installation
instructions.
8. Reboot the server.
9. Bring in all the paths and run the cfgmgr command.
10. Check all the paths to each disk using the lspath command. For example: lspath –l
hdisk3
VMware ESX Server
See “Deploying VMware ESX Server with SVSP” (page 122) for information on deploying a VMware
ESX server with SVSP.
Aligning file system partitions for Windows (pre-2008)
1. Windows Server 2008 does not have this problem, but for earlier versions of Windows, the
default partition set does not align the partition to the physical disk on which the partition
resides. Correct partition alignment helps reduce latency when the partition is written to,
because it eliminates the unnecessary disk writes and reads that occur when partitions are
not aligned. Windows partitions should be aligned at 64K for best results.
2. Partition alignment:
• Align partition with diskpart.exe for Windows 2000 or 2003, non SP1:
