Full Discussion: Where are my other disks on T5220 ?
Operating Systems Solaris Where are my other disks on T5220 ? Post 302987802 by hicksd8 on Friday 16th of December 2016 06:12:26 AM

You have used the STK RAID Live CD which DukeNuke2 told you to download to wipe existing RAID arrays from the STK controller. You can now see no disks from Solaris. That is correct behaviour.

Solaris will only see RAID arrays configured via the STK management suite (which on initialisation, will be automatically mapped to the host - Solaris).

It is likely that the previous sysadmin had a RAID1 (mirror) array configured for the root disk of 2 x 146GB giving a usable capacity of 146GB, plus a RAID5 array of 6 x 300GB for data giving a usable capacity of 1.5TB. That's why you could see only 2 disks originally.

Solaris will NOT see all 8 disks together only the result of each RAID array you create with the STK Manager as a single disk.

So you need to boot into the STK Manager again and create the arrays you want, then each of them will appear as a disk to Solaris.

Hope that helps.

kstat on T5220

We used kstat on netra240/440 to check if the link is full duplex. So we do something like: bash-3.00# kstat -pc net bge:1::/'link_duplex'/ | cut -f2 2 The output 2 indicates the link is full duplex. This kind of check worked all right for Netra 240/440 systems. However, the nxge... (2 Replies)

LEARN ABOUT NETBSD

ataraid

ATARAID(4)						   BSD Kernel Interfaces Manual 						ATARAID(4)

NAME

     ataraid -- software BIOS RAID

SYNOPSIS

     pseudo-device ataraid
     ld* at ataraid? vendtype ? unit ?

DESCRIPTION

     The ataraid driver provides support for BIOS-based software RAID controllers.  These are devices which have some simple support for several
     basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function.  The BIOS support is
     largely just to create and recognize the array so that it may be a boot device.

     The driver currently supports RAID formats from:
	   o   Adaptec HostRAID (found in Intel 6300ESB)
	   o   Intel MatrixRAID
	   o   JMicron RAID
	   o   nVidia MediaShield
	   o   Promise FastTrak
	   o   Via V-RAID (found in many VIA-based motherboards)

     Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility.

SEE ALSO

     ld(4), bioctl(8)

HISTORY

     The ataraid driver first appeared in NetBSD 2.0.

AUTHORS

     The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>.

BUGS

     Not all features of the software RAID are currently recognized or supported.  For example, the Adaptec support doesn't recognize when a RAID
     1 should be in a ``building'' state, and it does not do the right thing.

     At least part of the reason for this is that the publically-available information on these formats is quite limited.
