how do i know whether my server HP Integrity BL860 is booting from its HDD or from the SAN?
a storage person who came told me its not booting from SAN. but he didnt look at the OS.
but this is what i have:
db-server:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 30G 16G 13G 56% /
udev 8.0G 880K 8.0G 1% /dev
/dev/sda1 603M 22M 581M 4% /boot/efi
/dev/sda5 12G 6.8G 4.5G 61% /u02
/dev/sda4 9.9G 7.1G 2.3G 76% /p01
/dev/sda6 31G 25G 5.2G 83% /u01
/dev/sdl1 99G 45G 49G 49% /u07
/dev/sdb1 201G 38G 163G 19% /u03
db-server:~ # scsi_info /dev/sda
SCSI_ID="0,1,1,0":VENDOR="HP":MODEL="IR Volume":FW_REV="HP01":WWN="0000000008004625":LUN="600508e000000000-f6ffc6e4504a3805"
/dev/sda is where my OS resides.

Re: is my server booting from disk or SAN
scsi_info /dev/sdb
SCSI_ID="1,0,0,1":VENDOR="HP":MODEL="HSV300":FW_REV="0900":WWN="50014380025b5560":LUN="600508b4000a5537-00008000002e0000"
when i do a scsi_info of the other block devices. i get hsv300 against the model.
does that mean the one in my previous post is from the local hdd and this one is from storage.
In other servers (Intel x86_64) i find the root partition are shown as /dev/cciss/c0d0p2
whereas in this Itanium server
it is shown as /dev/sda3
does that mean the hardware raid is faulty

Yes, exactly.
Furthermore, "IR Volume" indicates it is a certain type of hardware RAID mirror.

No, it just means the Itanium server uses a different driver for the disk controller than the x86_64 server. According to specifications, the integrated disk/RAID controller in BL860c is LSI 1068.
The /dev/cciss device path is a characteristic of a certain group of hardware RAID controllers originally designed by Compaq and further developed by HP after Compaq and HP merged. These controllers were originally known by the name SmartArray, but recently HP marketing has started to complicate the situation by using the SmartArray name with different types of disk controllers too. So there is no good, clear name to describe exactly which group of controllers I mean :-(
