Problems AIX and SAN.
Sorry for my english.
We have a IBM BLADES JS21. AIX 5.3 update to 6.
Our JS21 has 2 FC (fcs0 and fcs1).
We have one DS4072, one Disk system with 2 controllers and 2 FC by controllers.
This means, all AIX FC see all Disk systems controllers by 2 FC switchs. (one fc two roads)
FC AIX -----> SWITCH A <----- 2 FC Controllers. A1 - B1
FC AIX -----> SWITCH B <----- 2 FC Controllers. A2 - B2
Is it support?. Because I only see one DAR (it is correct because I have only on partition on my Disk System). But I see 4 DAC ( DAC0 - DAC3 ) and I can not configure fault tolerant.
Thanks.

Hi All,
I have mirrored SAN volume on my B80 rootvg. Can I just remove the mirror and "Remove a P V from a V G" and it will be a diskless AIX?
Is that going to boot on SAN rootvg volume?
Thanks in advance,

Hi All,
I need to do maintenance on the SAN. Do I need to shutdown AIX as well? Or I can just unmount the SAN-FS and let the SAN reboot or do maintenance mode. And then when SAN is up, just mount it back.
Is that simple it is or not?
Thanks in advance,

CISS(4) BSD Kernel Interfaces Manual CISS(4)
NAME
ciss -- HP/Compaq Smart ARRAY 5/6 RAID controllers
SYNOPSIS
ciss* at pci? function ?
DESCRIPTION
The ciss driver provides support for the CISS interface implemented by fifth and later generations of the HP/Compaq Smart ARRAY family of
controllers.
The CISS interface is defined in the document entitled CISS Command Interface for SCSI-3 Support Open Specification, Version 1.04, Valence
Number 1, Compaq Computer Corporation, 2000/11/27.
This driver supports several Compaq and HP controllers implementing the CISS interface, including:
o Compaq Smart Array 5300 version 1
o Compaq Smart Array 5300 version 2
o Compaq Smart Array 5i version 1
o Compaq Smart Array 5i version 2
o HP Smart Array 5312
o HP Smart Array 6i
o HP Smart Array 641
o HP Smart Array 642
o HP Smart Array 6400
o HP Smart Array 6400 EM
o HP Smart Array E200
o HP Smart Array E200i
o HP Smart Array P400
o HP Smart Array P400i
o HP Smart Array P600
o HP Smart Array P800
o HP Smart Array V100
o HP Smart Array 1 through 13
These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.
Although the controllers are actual RAID controllers, the ciss driver makes them look just like SCSI controllers. All RAID configuration
must be done through the controllers' BIOSes.
Hardware from previous generations of this product family may be supported by the cac(4) driver.
SEE ALSO
bio(4), cac(4), intro(4), pci(4), scsi(4), sd(4)
HISTORY
The ciss driver first appeared in NetBSD 3.1.
AUTHORS
