migratepv

[alexia32]

Hello

stupid question but on hacmp env, I need to move some lv to new disks.
I have added the new disk to ha using cspoc. all good.
I suppose now i just need to use standard command migratepv -l to move the raw lv to the specific disks ?

Tx
Al

the C-SPOC's /usr/sbin/cluster/cspoc/smitlvm command supports:

# $1 = '-1' cl_chlv
# '-2' cl_chfs
# '-3' (namehdr for chlv)
# '-4' (namehdr for chfs)
# '-5' (namehdr) returns RGNAME:NAME
# '-6' cl_lslv
# '-7' cl_chlv dialog
# '-8' cl_rmlv
# '-9' cl_rmfs
# '-10' cl_chfs
# '-11' cl_lspvsmit
# '-12' cl_extendvg
# '-13' cl_reducevg
# '-14' cl_importvg
# '-15' cl_mirrorvg
# '-16' cl_unmirrorvg
# '-17' cl_mklv
# '-18' cl_extendlv
# '-19' cl_mklvcopy
# '-20' cl_rmlvcopy
# '-21' cl_syncvg
# '-22' (namehdr for disks) returns NODE:HDISK NAMES
# '-23' cl_lsfreedisks


I think you can try with cl_mklvcopy and after successfull cl_rmlvcopy from old disk. (I think it will work even if the LVCB is overwritten in your raw vlume (LV).)

Test it first somewhere on test env.

Thanks but I don;t have a test machine and it is real production.
I suppose migratepv should do it as it doesn't say anywhere we can;t use it.
the disks are configured HA...

I check again the man migratepv and see
"For concurrent mode volume groups migratepv can only be used while active in enhanced concurrent mode"
so I suppose it will work
I have a enhance concurrent VG (HA) with raw lv.
Too bad IBM can;t say HACMP support migratepv on bla bla bla...

Anyway if you have any information let me know

Cheers
Al.
