Solaris 10 Sparc. How to change Vendor info of SAN disks reported in "format" command?
Greetings!
After block level migration using an external appliance, the luns are getting reported as DGC-RAID5 and these luns are infact from the new storage. I have a query on changing the device Vendor info from DGC-RAID5 to HP3par in the format o/p only.
Code:
AVAILABLE DISK SELECTIONS:
2. c0t60002AC0000000000000000B0000xxxxd0 <DGC-RAID5-0430 cyl 51198 alt 2 hd 256 sec 16>
/scsi_vhci/ssd@g60002ac0000000000000000b0000xxxx
I am able to see the mpathadm and luxadm correctly reporting the device Vendor id as shown below.
Code:
luxadm display 20210002ac00xxxx DEVICE PROPERTIES for disk: 20210002ac00xxxx
Vendor: 3PARdata
Product ID: VV
Revision: 3213
Serial Num: 16xxxxx
Unformatted capacity: 103424.000 MBytes
Read Cache: Enabled
Minimum prefetch: 0x0
Maximum prefetch: 0xffff
Device Type: Disk device
Path(s):
/dev/rdsk/c0t60002AC0000000000000000B0000xxxxd0s2
Multipath definitions are configured ok and is reporting the actual paths.
However, format command reports them as DGC-RAID5 and adds a bit of confusion. Is there a way we can get the "format" command to get it reported correctly?
Thanks in advance!
BR,

I'm posting here as it didn't seem quite right in the hardware section (as it's LOM commands). My apologies if I have that wrong though :)

Hi, everyone.
I need to write a program to get io info based on libperfstat.
But the "write time" of a disk is just half of the value get from iostat.
I'm confused and can't explain. Help please.

addbadsec
addbadsec(1M) System Administration Commands addbadsec(1M)NAME
addbadsec - map out defective disk blocks
SYNOPSIS
addbadsec [-p] [ -a blkno [blkno...]] [-f filename] raw_device
DESCRIPTION
addbadsec is used by the system administrator to map out bad disk blocks. Normally, these blocks are identified during surface analysis,
but occasionally the disk subsystem reports unrecoverable data errors indicating a bad block. A block number reported in this way can be
fed directly into addbadsec, and the block will be remapped. addbadsec will first attempt hardware remapping. This is supported on SCSI
drives and takes place at the disk hardware level. If the target is an IDE drive, then software remapping is used. In order for software
remapping to succeed, the partition must contain an alternate slice and there must be room in this slice to perform the mapping.
It should be understood that bad blocks lead to data loss. Remapping a defective block does not repair a damaged file. If a bad block
occurs to a disk-resident file system structure such as a superblock, the entire slice might have to be recovered from a backup.
OPTIONS
The following options are supported:
-a Adds the specified blocks to the hardware or software map. If more than one block number is specified, the entire list should be
quoted and block numbers should be separated by white space.
-f Adds the specified blocks to the hardware or software map. The bad blocks are listed, one per line, in the specified file.
-p Causes addbadsec to print the current software map. The output shows the defective block and the assigned alternate. This option
cannot be used to print the hardware map.
OPERANDS
The following operand is supported:
raw_device The address of the disk drive (see FILES).
FILES
The raw device should be /dev/rdsk/c?[t?]d?p0. See disks(1M) for an explanation of SCSI and IDE device naming conventions.

The format(1M) utility is available to format, label, analyze, and repair SCSI disks. This utility is included with the addbadsec,
diskscan(1M), fdisk(1M), and fmthard(1M) commands available for x86. To format an IDE disk, use the DOS "format" utility; however, to
label, analyze, or repair IDE disks on x86 systems, use the Solaris format(1M) utility.
