HP SmartArray controller disk replacement steps on HP i2 blades

This is for the BL860c i2 blades (and other i2 models):

Replace a failed LVM mirror disk that is attached to a SmartArray SAS controller.

 

Notes:  For this example /dev/disk/disk2 is the failed disk and /dev/disk/disk4 is the new device that was created because the SAS controller identified a new disk.

Notes:  For this example the SAS controller device is /dev/ciss0

Notes:  The failed disk is in volume group vg00

 

Identify the disk by serial number.  Give the Bay number to the HP CE so they know which disk to replace:

sautil /dev/ciss0 -s

scsimgr get_info -D /dev/rdisk/disk2

 

Deactivate the PV:

pvchange -a n /dev/disk/disk2

 

Replace the failed disk.

 

Activate the WWID of the new disk.  The Error can be ignored.  A new disk device should be created:

scsimgr -f replace_wwid -D /dev/rdisk/disk2 dsf

scsimgr: ERROR: Cannot convert hardware path to an IO tree node

 

Find the new disk device that was created:

ioscan -fNnC disk

 

Create a description file to create the EFI partitions:

# cat >> /tmp/idf << EOF

3

EFI 500MB

HPUX 100%

HPSP 400MB

 

Use idisk to setup the disk partitioning on the new disk device:

idisk -wf /tmp/idf  /dev/rdisk/disk4

insf -e –C disk

 

Assign the old instance number to the replacement disk:

io_redirect_dsf -d /dev/disk/disk2 -n /dev/disk/disk4

 

Verify that /dev/disk/disk2 is in a claimed state:

ioscan –fnNC disk

 

Use mkboot to format and populate the newly created EFI partition:

mkboot -e -l /dev/disk/disk2

 

Change the AUTO file contents to the proper mode:

mkboot -a "boot vmunix -lq" /dev/rdisk/disk2

 

Restore the LVM reserved areas (PVRA/VGRA):

vgcfgrestore –n vg00 /dev/rdisk/disk2_p2

 

Reattach the new disk:

pvchange -a y /dev/disk/disk2_p2

 

Sync volume group:

vgsync vg00

 

Use lvlnboot to ensure that the LVM logical volumes are prepared:

lvlnboot -R

lvlnboot -v
