Re: hard disks superdome

The older MSA's (like MSA30) are just JBODs, an "ioscan -fn" may identify the device - but the other MSA's (e.g. MSA1000, MSA1500, MSA2000) may be listed in your "ioscan -fn" too. Post it, then we will see ...


Hope this helps!

Re: hard disks superdome

this superdome has four vm hosts and two RACs(each RAC has 2 to 3 vPars in it)

Re: hard disks superdome

The HSV300 is an EVA4400, this part looks like a DS21x0 disk enclosure:

 

ext_bus     4  0/0/8/1/0       mpt       CLAIMED     INTERFACE    SCSI Ultra320 A6961-60011
                              /dev/mpt4
target      8  0/0/8/1/0.0     tgt       CLAIMED     DEVICE
disk        4  0/0/8/1/0.0.0   sdisk     CLAIMED     DEVICE       HP 146 GST3146854LC
                              /dev/dsk/c4t0d0   /dev/rdsk/c4t0d0
target      9  0/0/8/1/0.2     tgt       CLAIMED     DEVICE
disk        5  0/0/8/1/0.2.0   sdisk     CLAIMED     DEVICE       HP 146 GST3146855LC
                              /dev/dsk/c4t2d0   /dev/rdsk/c4t2d0
target     10  0/0/8/1/0.4     tgt       CLAIMED     DEVICE
disk       10  0/0/8/1/0.4.0   sdisk     CLAIMED     DEVICE       HP 146 GST3146854LC
                              /dev/dsk/c4t4d0   /dev/rdsk/c4t4d0
target     12  0/0/8/1/0.6     tgt       CLAIMED     DEVICE
disk       12  0/0/8/1/0.6.0   sdisk     CLAIMED     DEVICE       HP 146 GST3146855LC
                              /dev/dsk/c4t6d0   /dev/rdsk/c4t6d0

 

 

So you probably have 2 DS21x0 disk enclosures (for mirroring) connected to each nPar with local disks. This is indicated by the SCSI IDs of 0, 2, 4 and 6 (switch position "A" at the enclosure). Somebody should have a look at the rack!

 


Hope this helps!

Torsten.

Re: hard disks superdome

No MSA at all!

But a DS21x0, see http://h18006.www1.hp.com/storage/disk_storage/disk_systems/ds2120/index.html

Re: hard disks superdome

Thanks, how did you deduced it?


also... do u want to see scan output from MON prompt?
no need of any other information ?
any output from any vPar needed?

I am just trying to confirm before passing on this info to my superiors.

Re: hard disks superdome

An MSA would look like this in ioscan:

 

MSA30:

ctl         5  0/2/1/0/4/0.15.0  sctl      CLAIMED     DEVICE       COMPAQ  PROLIANT 4L7E*DB

 

P2000:

3/0/0/7/0/0/1.1.14.0.0.0.0                                       disk    HP      P2000 G3 FC

 

MSA1000/1500:

disk     14  64000/0xfa00/0x2  esdisk   CLAIMED     DEVICE       COMPAQ  MSA1000 VOLUME

 


The DS2120 does not show up in ioscan, because there is nothing else than disks. But depending on the chassis switch position it has fixed SCSI IDs for the maximum of 4 disks - 0,2,4,6 - this is what you have!

 

The DS2120 was also kind of "default" local disk hardware for this generation of superdome.
 


Hope this helps!

Torsten.

We are trying to find out if we have any large disks (may be more than 300GB)

Attached document shows u the conversations we had..

Re: hard disks superdome

These are 2.5-inch (SFF) Dual-Port SAS drives - you don't have any of them!

If you are worried about HDD firmware, I would recommend to check your EVA4400 (but these are FC disks)!

Hope this helps!

Re: hard disks superdome

does that mean..we dont have any disks larger than 300GB? or we dont have any MSA? or both?

I would also like to know how did you deduce that these are: 2.5-inch (SFF) Dual-Port SAS drives ...because they are DS2120 or because of any other reason?

thanks fro your replies
Torsten.

Re: hard disks superdome

The advisory you posted tells about these 2,5" SAS drives (by the way, the advisory is related to a smartarray - you don't have a smartarray controller, you don't have a MSA).

 

Have a look at your ioscans:

 

disk        4  0/0/8/1/0.0.0   sdisk     CLAIMED     DEVICE       HP 146 GST3146854LC
                              /dev/dsk/c4t0d0   /dev/rdsk/c4t0d0

 

These are 146GB parallel SCSI drives, no SAS at all.

 

Your EVA4400 may have larger disks, but the advisory does not apply to fibre channel drives!


Hope this helps!
Regards
Torsten.

Re: hard disks superdome

Just to complete - this is what you see as "HSV300" (in fact an EVA4400 disk array:
