Re: 512 to 522 disk format

Weird, I booted from the 7.1.1 Aix Diagnostics, and made the disks "raid
candidate" (that's their terminology for 522 bytes/sector). IBM i 7.1 STILL
sees them as 6600 and doesnt allow format, disks are marked eServer
pSeries 10N7234... I'll see if there's any other option on the AIX
diagnostics, but i'm starting to think they don't want to have anything to
do with IBM i. Shame as i got a cartload of 146's and a handfull of 300's.

There were some older drives that had firmware in them to prevent the

Well, 7.1 LIC didnt like the disks either, same "IO error" on all disks.
I'm burning the AIX diagnostics which is used to do the reverse (522 to
512) and i'll see if it has the 512 to 522 option. I'd really like to turn
all of those disks to IBM i since i have more of those machines...

Jim, I know that i can not install LIC into a DPH'ed drive and i must
Format & Initialize first, but on that screen (Format and Initialize)
is that i get the i/o error. As soon as i get a moment i'll re-hook it
up to the HMC and test with 7.1's LIC DVD just to be sure.

Best Regards,

You tried to install LIC before you initialized the drive. That
drive is read only (the H in the name gives that away)

Go into disk recovery and reformat the drives before you try and load

LIC.

Jim, At least with the v5r4m5 I_BASE i just used the initialize
option ends up with I/O error and a surface scan ends with "not
supported", The disks appear as 6600 and DPHXX, maybe i have to use a
7.1 I_Base? i'm not sure when that re-format procedure appeared...

If I read you correctly you want to take a disk formatted for AIX
and use it on IBM i.

Boot from DVD into DST if needed or STRSST

Work Disk Units
Work with Disk unit recovery
Disk unit problem recovery procedures Initialize and format disk
unit

By the time you're done you'll have model 50 drives of the
appropriate type.

Subject: 512 to 522 disk format

I remember Dr Franken mentioning that with SAS disk there is a way
to format 300Gb disks into 281Gb and vice-versa, i just got a batch
of 300Gb which of course appear as 6600 to my I_BASE_01, i was
wonderin how exactly that format can be applied, maybe i have to
hook them up to a VIOS partition?
(that would be time-consuming as my vios machines dont have 3.5"
bays) Or maybe it's related to the linux iprconfig tool i googled?
Well if anyone knows, i may put those disks to good use...

Best Regards,

Roberto Etcheverry
