sasmgr reports 'block size not supported' when trying to add disks

rx3600 with the 8-port PCI-X SAS controller and running under UX 11.23.

Recently installed 2 x 300GB SAS drives to exsting server which has 2x72GB in raid-1 pair and 2x146GB in raid-1 pair, but sasmgr comes back with "Block size not supported - min 512 max 2097152" error if I try to create raid-1 pair using the new 300GB drives.

I don't see any means to query the block size of these news drives to start with, as they can only be 'seen' by the SAS controller.

Does anyone have any suggestions please?

sasmgr info I can get so far is:

Re: sasmgr reports 'block size not supported' when trying to add disks

This controller can only do 2 mirrored pairs of drives plus hotspare. all other disks can only presented as plain disks.


Hope this helps!
Regards
Torsten.

Re: sasmgr reports 'block size not supported' when trying to add disks

Hello Torsten and thank you so much for the very prompt reply.

You have confirmed my worst thoughts about this controller then!

Is it a simple matter to add as JBOD?   (As I don't see any examples of doing this in any of the sasmgr documentation I've got to hand).

This particular server is just an off-site D/R box, so I'm sure we could live without RAID on some disks (there is an on-site 'mirror' of the production server too as first failover point).

 

Regards

Paul

Re: sasmgr reports 'block size not supported' when trying to add disks

see quickspec https://www.hpe.com/h20195/v2/getpdf.aspx/c04140688.pdf?ver=24

The PCI X 8 port Serial Attached SCSI (SAS) host bus adapter: Card will be installed in reserved core PCI X I/O slot #1.
This card supports up to two internal RAID 1 volumes (2├Ч2 HDDs) and a disk for global hot spare, for a maximum of
five disks in RAIDed arrays for HP UX and OpenVMS.
 
...
 
But you can mirror the remaining disks using LVM, no problem.
It is just a bit harder to replace a bad disk ... ;-)

Hope this helps!
Regards
Torsten.
