Thanks this helps I will make sure the microcode/firmware is up to the latest available before I move this into production.
This is a standalone box, so no LPM.

Hey bakunin,
Here is a question for you on pv/vg in regards to my new system setup...
I have carved a 350GB LUN from my StorWize SAN and presented it to the Power8 box via FC.
The pv hdisk2 has the following attributes (the hdisk2 is the LUN I carved and presented)..
Code:
# lspv hdisk2
PHYSICAL VOLUME: hdisk2 VOLUME GROUP: vg_usr2
PV IDENTIFIER: 00f9af9427d70816 VG IDENTIFIER 00f9af9400004c000000014b28233d7d
PV STATE: active
STALE PARTITIONS: 0 ALLOCATABLE: yes
PP SIZE: 512 megabyte(s) LOGICAL VOLUMES: 1
TOTAL PPs: 699 (357888 megabytes) VG DESCRIPTORS: 2
FREE PPs: 0 (0 megabytes) HOT SPARE: no
USED PPs: 699 (357888 megabytes) MAX REQUEST: 256 kilobytes
FREE DISTRIBUTION: 00..00..00..00..00
USED DISTRIBUTION: 140..140..139..140..140
MIRROR POOL: None
After some googling I understand that a normal VG is limited to 32512 physical partitions (32 physical volumes each with 1016 partitions) and 256 logical volumes.
Now I am already confused, hope you can demystify some stuff..
My "hdisk2" has 699 total physical partitions (Total PPs?) based on PP Size being 512mb chunks. So this is 699 out of 32,512 or 1016?
If I changed the hdisk2 to have a PP Size of 256mb chunks, the Total PPs would be 1398 correct? Is there any performance benefits of making the PP Size smaller vs. larger? I am trying to decide what I want my PP Size to be for the PVs.
In the end I will have 4 enhanced JFS2 FS each allocated 350GB, 1TB, 1T, and 2.45TB.

Hello,
I have IBM SAN STORAGE DS4100 and one of the cache battery for the controller is dead. Suddenly the performance has been degraded and access to SAN disks ( reading and writing ) became very slow ?

Has anyone tried SAN to SAN mirroring on IBM DS SAN Storage.
DS5020 mentions Enhanced Remote Mirror to multi-LUN applications
I wonder if Oracle High availibility can be setup using Remote Mirror option of SAN ? (1 Reply)

Hello,
We have an Power8 System (S822) and a IBM StorWize v3700 SAN.
The OS is AIX 7.1.

TR(4) BSD Kernel Interfaces Manual TR(4)NAME
tr -- TROPIC based shared memory Token-Ring cards device driver
SYNOPSIS
tr0 at isa? port 0xa20 iomem 0xd800 irq ?
tr* at isa? port ? irq ?
tr* at isapnp?
tr* at mca? slot ?
tr* at pcmcia? function ?
DESCRIPTION
The tr device driver supports TROPIC I based shared-memory Token-Ring cards.
HARDWARE
Supported cards include the following IBM and 3Com models:
IBM Token-Ring Network PC Adapter
IBM Token-Ring Network PC Adapter II
IBM Token-Ring Network Adapter/A
IBM Token-Ring Network 16/4 Adapter
IBM Token-Ring Network 16/4 Adapter/A
IBM Token-Ring 16/4 Credit Card Adapter
IBM Token Ring Auto 16/4 Credit Card Adapter
IBM Turbo 16/4 Token Ring PC Card
IBM 16/4 ISA Adapter
IBM Auto 16/4 Token-Ring ISA Adapter
IBM Token Ring 16/4 Credit Card Adapter
IBM Token Ring Auto 16/4 Credit Card Adapter
IBM Turbo 16/4 Token Ring PC Card
3Com 3C619 TokenLink
3Com 3C319 TokenLink Velocity
3Com 3C389 TokenLink Velocity PC Card
SOURCE ROUTING
Setting IFF_LINK0 enables Token-Ring source routing. Setting IFF_LINK1 uses all-routes broadcasts otherwise single-route broadcasts are
used.
NOTES
The MCA attachment has been only tested on IBM Token Ring 16/4 Adapter/A so far. It doesn't support ifmedia(4) yet, too.
SEE ALSO ifmedia(4), intro(4), isa(4), isapnp(4), mca(4), pcmcia(4), ifconfig(8)HISTORY
The tr driver appeared in NetBSD 1.4.
BUGS
The PCMCIA attachment does not work with the cbb(4) CardBus driver.
