Hi:
I am in the process of configuring the SAN for Solaris to host 6 oracle 9i databases. We have 30 -146 GB disks stiped with RAID 10 for SAN. Of which 11 are dedicated for databsaes related things. Then we have 2 v880 Sun Servers with 16 -73 GB disks and 24 GB memory.

Hi all,
Sorry if this is in the wrong place but needed to make sure lots of people saw this so that hopefully someone will be able to help.
Basically i've upgraded a test server from 4.3 to 5.3 TL04.
The server has hdisk0 and 1 as rootvg locally but then has another vg setup on our ESS... (5 Replies)

Hi,
I have a strange problem. we're trying to connect an IBM pseries, to a Brocade switch, for SAN acess, using a badged emulex card, (IBM FC6239) WE can configure the device to see the fabric. The only problem we have is that the Brocade sees the HBA as storage, and not as a HBA.

Sorry for my english.
We have a IBM BLADES JS21. AIX 5.3 update to 6.
Our JS21 has 2 FC (fcs0 and fcs1).
We have one DS4072, one Disk system with 2 controllers and 2 FC by controllers.
This means, all AIX FC see all Disk systems controllers by 2 FC switchs. (one fc two roads)

I have some T3's we just purchased and we are looking to carve these up into LDOMS's.
Just wondering if anyone can give me a quick run down or pro / cons on SAN vs local internal for the LDOM itself. These will external SAN storage for their applications. (0 Replies)

ZPTRFS(l) ) ZPTRFS(l)
NAME
ZPTRFS - improve the computed solution to a system of linear equations when the coefficient matrix is Hermitian positive definite and
tridiagonal, and provides error bounds and backward error estimates for the solution
SYNOPSIS
SUBROUTINE ZPTRFS( UPLO, N, NRHS, D, E, DF, EF, B, LDB, X, LDX, FERR, BERR, WORK, RWORK, INFO )
CHARACTER UPLO
INTEGER INFO, LDB, LDX, N, NRHS
DOUBLE PRECISION BERR( * ), D( * ), DF( * ), FERR( * ), RWORK( * )
COMPLEX*16 B( LDB, * ), E( * ), EF( * ), WORK( * ), X( LDX, * )
PURPOSE
ZPTRFS improves the computed solution to a system of linear equations when the coefficient matrix is Hermitian positive definite and tridi-
agonal, and provides error bounds and backward error estimates for the solution.
ARGUMENTS
UPLO (input) CHARACTER*1
Specifies whether the superdiagonal or the subdiagonal of the tridiagonal matrix A is stored and the form of the factorization:
= 'U': E is the superdiagonal of A, and A = U**H*D*U;
= 'L': E is the subdiagonal of A, and A = L*D*L**H. (The two forms are equivalent if A is real.)
N (input) INTEGER
The order of the matrix A. N >= 0.
NRHS (input) INTEGER
The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
D (input) DOUBLE PRECISION array, dimension (N)
The n real diagonal elements of the tridiagonal matrix A.
E (input) COMPLEX*16 array, dimension (N-1)
The (n-1) off-diagonal elements of the tridiagonal matrix A (see UPLO).
DF (input) DOUBLE PRECISION array, dimension (N)
The n diagonal elements of the diagonal matrix D from the factorization computed by ZPTTRF.
EF (input) COMPLEX*16 array, dimension (N-1)
The (n-1) off-diagonal elements of the unit bidiagonal factor U or L from the factorization computed by ZPTTRF (see UPLO).
B (input) COMPLEX*16 array, dimension (LDB,NRHS)
The right hand side matrix B.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
X (input/output) COMPLEX*16 array, dimension (LDX,NRHS)
On entry, the solution matrix X, as computed by ZPTTRS. On exit, the improved solution matrix X.
LDX (input) INTEGER
The leading dimension of the array X. LDX >= max(1,N).
FERR (output) DOUBLE PRECISION array, dimension (NRHS)
The forward error bound for each solution vector X(j) (the j-th column of the solution matrix X). If XTRUE is the true solution
corresponding to X(j), FERR(j) is an estimated upper bound for the magnitude of the largest element in (X(j) - XTRUE) divided by
the magnitude of the largest element in X(j).
BERR (output) DOUBLE PRECISION array, dimension (NRHS)
The componentwise relative backward error of each solution vector X(j) (i.e., the smallest relative change in any element of A or B
that makes X(j) an exact solution).
WORK (workspace) COMPLEX*16 array, dimension (N)
RWORK (workspace) DOUBLE PRECISION array, dimension (N)
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
PARAMETERS
ITMAX is the maximum number of steps of iterative refinement.
