===== Smartctl hints for HP smart array (HPSA driver) =====

The HPSA driver was introduced with RHEL6 to the RHEL family.

  Drive0:
  # smartctl -a -d cciss,0 /dev/sg0
  
  Drive1:
  # smartctl -a -d cciss,1 /dev/sg0
  
Ref: man smartctl

===== List HP array information =====

  # lsscsi --long

  Alternatively
  
  # dmesg | grep "^scsi "

===== Display mapping between linux sg and other SCSI devices  =====

Requires installation of sg3_utils RPM.

  # sg_map
  /dev/sg0
  /dev/sg1  /dev/sda
  /dev/sg2  /dev/sdb
  /dev/sg3  /dev/sdc
  /dev/sg4  /dev/sdd
  /dev/sg5  /dev/sde
  /dev/sg6  /dev/sdf
  /dev/sg7  /dev/sdg
  /dev/sg8  /dev/sdh
  /dev/sg9  /dev/sdi

Reference: man sg_map

Alternatively:

  # lsscsi -g
  [3:0:0:0]    storage HP       P410i            5.14  -         /dev/sg0

====== LSI Raid Utils ======

LSI raid controller


===== Find disk device for logical driver under LSI raid controller =====
 


First list the Logical Drives (LD's)

  # /opt/MegaRAID/MegaCli/MegaCli64 -ldinfo -Lall -aall 
  Adapter 0 -- Virtual Drive Information:
  Virtual Drive: 0 (Target Id: 0)
  Name                :
  RAID Level          : Primary-1, Secondary-0, RAID Level Qualifier-0
  Size                : 837.258 GB
  Mirror Data         : 837.258 GB
  State               : Optimal
  Strip Size          : 128 KB
  Number Of Drives    : 2
  Span Depth          : 1
  Default Cache Policy: WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU
  Current Cache Policy: WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU
  Default Access Policy: Read/Write
  Current Access Policy: Read/Write
  Disk Cache Policy   : Disabled
  Encryption Type     : None
  PI type:  Proprietary type

  Is VD Cached: No

  Virtual Drive: 1 (Target Id: 1)
  Name                :
  RAID Level          : Primary-1, Secondary-0, RAID Level Qualifier-0
  Size                : 1.634 TB
  Mirror Data         : 1.634 TB
  State               : Optimal
  Strip Size          : 128 KB
  Number Of Drives per span:2
  Span Depth          : 2
  Default Cache Policy: WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU
  Current Cache Policy: WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU
  Default Access Policy: Read/Write
  Current Access Policy: Read/Write
  Disk Cache Policy   : Disabled
  Encryption Type     : None
  PI type: No PI

So the target ID is 0 for VD 0 and the Target ID is 1 for VD 1

Find target ID to Disk Device translation

  #lsscsi 
  [0:0:19:0]   enclosu IBM-ESXS SAS EXP BP       6126  -       
  [0:0:36:0]   enclosu IBM-ESXS SAS EXP BP       6126  -       
  [0:2:0:0]    disk    IBM      ServeRAID M5110  3.19  /dev/sda 
  [0:2:1:0]    disk    IBM      ServeRAID M5110  3.19  /dev/sdb 
  [0:2:2:0]    disk    IBM      ServeRAID M5110  3.19  /dev/sdc 
  [0:2:3:0]    disk    IBM      ServeRAID M5110  3.19  /dev/sdd 
  [0:2:4:0]    disk    IBM      ServeRAID M5110  3.19  /dev/sde 
  [0:2:5:0]    disk    IBM      ServeRAID M5110  3.19  /dev/sdf 
  [1:0:0:0]    cd/dvd  IBM SATA DEVICE 81Y3664   IBA1  /dev/sr0 


So Target ID 0 = 0:2:0:0 (the target ID is the digit after 2:) equals sda
So Target ID 1 = 0:2:1:0 (the target ID is the digit after 2:) equals sdb

lsscsi command can be found in lsscsi.x86_64 package
