Remove duplicated bootlist entries
Hello.


I have a server with 2 boot disk but in the bootlist there are 5 paths of one disk but no path of the other.
How can I remove paths from one disk to insert paths from the other disk?

Thanks in advance.



Code:
server074:root:/# bootlist -om normal
hdisk0 blv=hd5 pathid=0
hdisk0 blv=hd5 pathid=1
hdisk0 blv=hd5 pathid=2
hdisk0 blv=hd5 pathid=3
hdisk0 blv=hd5 pathid=4

server074:root:/# bootlist -m normal hdisk0 hdisk3

server074:root:/# bootlist -om normal
hdisk0 blv=hd5 pathid=0
hdisk0 blv=hd5 pathid=1
hdisk0 blv=hd5 pathid=2
hdisk0 blv=hd5 pathid=3
hdisk0 blv=hd5 pathid=4

Can you show us the output from:-
Code:
lsvg rootvg
lsvg -l rootvg
lsvg -p rootvg

How are your disks provided and connected? It would be good to know how you have generated 5 paths. It's not necessarily a problem, just a little unusual.

If these are SAN/VIO etc provided, then there may not be a need to mirror and assign the bootlist to both (or all)


Kind regards,
Robin

Yes, of course. Here there are ...
Code:

hdisk3  Available 12-T1-01 HP HSV450 Enterprise Virtual Array



The 5 paths were generated when the rootvg wasn't mirrorred.
We have just mirrored the rootvg, and added the bosboot.

Kind regards.

Code:
 
  •   bootlist -m normal hdisk0 pathid=0,2
    • 

  •   bootlist -m normal hdisk0 pathid=0 hdisk0 pathid=2
    •

It is IBM's (?) OpenFirmware limitation, that you can have up to 5 devices in the boot list. Every path is seen as a separate device in OF. Check your paths with lspath command, but in a general case you don't need to many paths to each device. 2 or 4 paths are enough most of times. Remove unnecessary paths with rmpath command.

Great !!! Thank you very much

Code:
server074:root:/# bootlist -m normal hdisk0 pathid=0,2 hdisk3

server074:root:/# bootlist -om normal
hdisk0 blv=hd5 pathid=0
hdisk0 blv=hd5 pathid=2
hdisk3 blv=hd5 pathid=0
hdisk3 blv=hd5 pathid=2
hdisk3 blv=hd5 pathid=3

I notice that you have the following in the output of lsvg -l rootvg
Code:
lg_dumplv1          sysdump    8       8       1    open/syncd    N/A

Is this intentional? I have seen both a mirror on the dump device and a secondary dump device allocated on the 'other' disk in rootvg. I'm not sure which one is more sensible, but if hdisk0 failed, you would ungracefully lose your dump device and might have trouble recreating it.

Actually, I'm not sure why. This is the dump configuration:
Code:
server074:root:/# sysdumpdev -l
primary              /dev/lg_dumplv1
secondary            /dev/sysdumpnull
copy directory       /var/adm/ras
forced copy flag     FALSE
always allow dump    TRUE
dump compression     ON
type of dump         traditional

I have created another LV in the other disk:
Code:
server074:root:/# lspv -l hdisk3 | grep dump
livedump              2       2       01..01..00..00..00    /var/adm/ras/livedump
lg_dumplv1            8       8       08..00..00..00..00    N/A

server074:root:/# lspv -l hdisk0 | grep dump
lg_dumplv2            8       8       08..00..00..00..00    N/A
livedump              2       2       02..00..00..00..00    /var/adm/ras/livedump

server074:root:/# sysdumpdev -Ps /dev/lg_dumplv2
primary              /dev/lg_dumplv1
secondary            /dev/lg_dumplv2
copy directory       /var/adm/ras
forced copy flag     FALSE
always allow dump    TRUE
dump compression     ON
type of dump         traditional
