Configure new disk

Configure new disk

High level description

• 0.1) remove the disk in the db array as a spare from the system array (this was a workaround for something strange)
• 0.2) assign the spare disk in the work array as a spare
• 1) create new raid 1+0 arrays for each chassis then assign slot 25 as a spare
• 2) assign each to a physical volume
• 3) create a volume group for each
• 4) create a logical volume for each
• 5) create a file system on the logical volume
• 6) Add to fstab & mount
• 7) Add to nfs exports and restart nfsd

Steps 0.1 though 1 are done using the HP controller proprietary software. the rest are done as root on the command line

Note

• 1) there is a spare assigned to array A
• 2) everything is working off of the controller in "slot 1" (the good one)
• 3) the dell box does not know how to distinguish drives (the IDs are all the same)
• 4) we have lots of spares

Command line description

As root on fawlty:

/opt/compaq/hpacucli/bld/hpacucli

then inspect the current configuration:

ctrl all show config

To remove the spare let's just remove all spares (we haven't assigned any important ones yet) run the following command:

ctrl slot=1 array A remove spares=all

create arrays (logical disk with all the disks in a specific chassis)

ctrl slot=1 create type=ld drives=1E:1:1-1E:1:24 raid=1+0
ctrl slot=1 create type=ld drives=4E:1:1-4E:1:24 raid=1+0

(for the second array)

add spares

ctrl slot=1 array A add spares=3E:1:25
ctrl slot=1 array D add spares=1E:1:25
ctrl slot=1 array E add spares=3E:1:25

pvcreate /dev/sde
