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!

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 :)

I have a bunch of random character lines like ABCEDFG. I want to find all lines with "A" and then change any "E" to "X" in the same line. ALL lines with "A" will have an "X" somewhere in it.

sg_luns
SG_LUNS(8) SG3_UTILS SG_LUNS(8)NAME
sg_luns - send the SCSI REPORT LUNS command
SYNOPSIS
sg_luns [--decode] [--help] [--hex] [--maxlen=LEN] [--quiet] [--raw] [--select=SR] [--verbose] [--version] DEVICE
DESCRIPTION
Send the SCSI REPORT LUNS command to the DEVICE and outputs the response. In the SPC-3 SCSI standard support for this command is mandatory.
OPTIONS
Arguments to long options are mandatory for short options as well.
-d, --decode
decode logical unit numbers into their hierarchical parts. Interprets luns as described in SAM-3 when the HiSup bit is set in a
standard INQUIRY's response.
-h, --help
output the usage message then exit.
-H, --hex
output response to this command in ASCII hex.
-m, --maxlen=LEN
where LEN is the (maximum) response length in bytes. It is placed in the cdb's "allocation length" field. If not given (or LEN is
zero) then 8192 is used. The maximum allowed value of LEN is 65536.
-q, --quiet
output ASCII hex rendering of each report lun, one per line.
-r, --raw
output response in binary (to stdout).
-s, --select=SR
this option sets the 'select report' field (SR) in the SCSI REPORT LUNS command. The default value is 0. When 0 is given (or this
option is not specified) then the DEVICE should yield a list of luns addressable via this "I_T nexus" that use the following lun
addressing methods: logical unit addressing, peripheral device addressing and flat space addressing. When 1 is given the DEVICE
should yield a list of only "well known" logical units addressable via this "I_T" nexus. When 2 is given the DEVICE should yield all
luns addressable via this "I_T" nexus. To simplify, for the I_T nexus associated with the DEVICE, the meanings of the SR values
are:
0 : all luns excluding well known logical units
1 : well known logical units
2 : all luns
Values between 0xf8 and 0xff (inclusive) are vendor specific (SPC-4 (rev 32), other values greater than 2 are reserved.
-v, --verbose
increase the level of verbosity, (i.e. debug output).
-V, --version
print the version string and then exit.
EXIT STATUS
The exit status of sg_luns is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
