Can I show the HBA link speed from OpenVMS??
I've been searching for a way to show the link speed of the HBAs (FG devices) from VMS without going to the FC switch. I haven't been able to do it with anal/sys fc commands. Maybe I'm missing something easy...
Even if I could just show the current connection speed that would be cool, versus all the possible speeds.
Thanks!!
Tom

Re: Can I show the HBA link speed from OpenVMS??

The answer is yes, if you're willing to work for it. When we first did these drivers there was only 1 link speed so it was never extracted into an SDA extension display - it should be now, though, as this isn't the first time we've been asked this question
For Qlogic:
SDA> FC SET DEVICE FGA ! Or FGB, etc.
SDA> EXAMINE LSDB+LSDB$L_LINK_DATA_RATE
! 0 = 1G, 1 = 2G, 2 = 4G
For Emulex:
SDA> FC SET DEVICE FGA ! Or FGB, etc.
SDA> EXAMINE @(@(LSDB+LSDB$PS_READ_LA_FCCD)+FCCD$PS_MBX_RSP)+8*4
SDA>
! In bits 15:8, 0 = down, 4 = 1G, 8 = 2G, 0x10 = 4G

Re: Can I show the HBA link speed from OpenVMS??
Perhaps I misunderstood...I'm not that great with SDA. I seem to get the wrong output for a 1gb Emulex, but it works for the 2gb Emulex. These devices are online and paths are connected thru them. It appears to me that I do get the value of 8 in that byte (bits 8 thru 15) for the 2gb. Also did 0x10 mean %x10 as in Hex A?
SDA> FC SET DEVICE FGA ! 1GB Emulex
SDA> EXAMINE @(@(LSDB+LSDB$PS_READ_LA_FCCD)+FCCD$PS_MBX_RSP)+8*4
SPDT+00CF0: 00000000.0000000A "........"
-------------------------------------
SDA> FC SET DEVICE FGA ! 2GB Emulex
SDA> EXAMINE @(@(LSDB+LSDB$PS_READ_LA_FCCD)+FCCD$PS_MBX_RSP)+8*4
FCLE_RCTX+00BF0: 00000000.0000080A "........"
Thanks again!

Re: Can I show the HBA link speed from OpenVMS??
The 2GB cards are on another machine. Its the 1GB units that don't report correctly, presuming I'm doing everything right.
Sorry for that confusion, and I see how that was very misleading. I just wanted to show both FGA and B which are both the same type and as you indicated.
To Peter and Robert, thanks for the note. Yes we can and have looked at the switches. Its just kinduv a pain with a big SAN... It would be so nice to just pop it out from VMS.
Thanks again!!
Tom
